Operating requirements

Electrical

Make sure the line voltage meets the requirements. See Specifications on page 103 for details.
Use the supplied power cord. Plug it directly into a grounded electrical outlet. Do not lengthen the power cord with an extension cord; the resulting drop in voltage could damage the printer.
To maintain vacuum to the printheads during printer power-down or unexpected power outages, use the auxiliary 24 volt power supply (included in the accessory kit with universal power adapters). Connect the 24 VDC jack on the vacuum assembly to either of two options:
UPS Customer-supplied uninterruptable power supply, output 100-240 VAC, 50/60 Hz, minimum of 15 watts of power, provides battery backup to the vacuum system in the event of a power failure.
Wall outlet 100-240 VAC, 50/60 Hz, provides temporary power to the vacuum system when it is necessary to power down the printer for service. See Appendix A, Technical Specifications, for details.
Connect printer to its own electrical circuit. Do not connect the RIP, auxiliary power supply, or UPS into the same circuit as the printer.

Environmental

Make sure the room is well ventilated, with a temperature and relative humidity within specifications. Optimal printing occurs within these ranges. See Specifications on page 103 for details.
The high power UV light emitted by the curing lamps reacts with oxygen and produces ozone. This formation tends to be greatest during lamp startup. The printer should be operated in a well-ventilated area to avoid minor effects such as headaches, fatigue, and dryness of the upper respiratory tract. Normal air movement will mix the ozone with fresh air, causing it to revert back to oxygen.
Store media and ink in an area with similar temperature and humidity conditions as the printer.
Locate the printer so that it can be connected to the RIP with the specified cable.
Locate the printer on a flat, level floor.
Locate the printer where its normal operating noise will not disturb quiet work areas.
DO NOT install the printer near humidifiers, refrigerators, fans, water faucets, heaters or similar equipment.
DO NOT install the printer in areas where the temperature changes abruptly, such as near air conditioners, in the path of direct sunlight, or near open doors or windows.
DO NOT expose the printer to flames or dust.

RIP

The printer receives print jobs from a supported raster image processor (RIP). The RIP is installed and connected during the printer installation process.

2  Chapter 1 Introduction  ENWW

Important operating notes

UV CURE INK IS PERISHABLE. Unlike other inks used in wide format printing, UV cure ink has a limited shelf life. White ink has a six month shelf life from the date of manufacture. Plan to rotate your ink stock and use it promptly by the date printed on the ink box.

image5

image6 CAUTION: When the UV lamps are switched off, they undergo a controlled cool-down cycle. Sudden removal of power from hot lamps, such as disconnecting the power cord or from a power outage, can result in overheating and permanent damage. The lamps should be switched off only via the printer software.

image7 NOTE:  A customer-supplied UPS will not support the UV cool-down cycle.

image8image9

The media supply may be wound either printed-side-out or printed-side-in, but the takeup must be loaded printed-side-in.
The default head height is set to 2.2 mm (0.085 in) above the media. (The space below the carriage will measure 1.78 mm (0.070 in) due to the printhead protection frame around the outside of the carriage.) The head height can be adjusted up or down at the control panel (Printing > Options).
The Media Wizard stores a set of operational parameters for predefined and user-defined media types. When you load a new media type, select an existing Media Wizard set, or create a custom set. Media Wizard parameter sets can be selected at any time from the control panel.
Wear cotton gloves when loading media to prevent fingerprints that could show after printing. You can use a 90% solution of isopropyl alcohol (IPA) to clean fingerprints and reduce static electricity on synthetic media (allow to dry five minutes before printing).
DO NOT reprint over any output that has not completely cured (for example, due to a UV lamp malfunction).
DO NOT rest or store a media roll on end, or you could cause edge creases that could strike the printheads during printing. To avoid bowing, store sheet-fed media flat, not standing on end.
DO NOT set heavy objects on the power cord or printer cable; do not bend the cables or force them into contorted positions.
DO NOT place heavy objects anywhere on the printer.
Since automatic head maintenance cannot occur when the printer is powered down, keep the printer powered on at all times if possible. The printer will enter a power-saving Sleep Mode if idle for a user-defined period of time. If automatic head maintenance does not occur for an extended period, manual purging may be necessary to restore the printheads to working condition (see Startup and check jet health on page 114). If all power is lost to the printer, ink will drip from the printheads due to loss of printhead vacuum, collect on the bottom of the carriage, and drip into the printer or onto the media drive belt. Keep the printer connected to a UPS to prevent vacuum loss to the printheads (see Electrical on page 2).
If the printer will be completely powered down for an extended period (such as over a long holiday period), all printheads should be emptied of ink (see Printhead Procedures under Maintenance menu on page 41) and the bottom of the carriage cleaned. To resume printing, the printheads must be refilled with ink, purged, and restored to working condition. See User cleaning on page 74 and Startup and check jet health on page 114 for instructions.

ENWW  Important operating notes  3

Safety warnings

UV light The ultraviolet (UV) curing lamps emit high power UV light. The printer must be operated with all safety shielding installed to protect the operator from eye and skin damage. When operated according to manufacturer’s instructions, safety glasses or other protective clothing are not necessary.
Mechanical hazards Keep fingers away from carriage and media path. Do not exceed the maximum weight load of the input or output tables, as printed on the label.
Ink Read and practice safety guidelines as outlined in the Material Safety Data Sheet (MSDS) for the ink, and post the document in the work area as required by prevailing law. Avoid any contact with skin and eyes. Provide adequate general and local exhaust ventilation. Avoid breathing vapors. Respirator protection may be required under exceptional circumstances when excessive air contamination exists. None of the component substances have established exposure standards per OSHA, NIOSH, or ACGIH. Collect waste ink in container provided. Dispose of ink according to MSDS and local regulations. Keep the waste-ink spigot closed during printing.
Special ventilation is not required to meet US OSHA requirements on occupational exposure to VOCs from the HP UV-curable inks used with the printer. Special ventilation equipment installation is at the discretion of the customer; no specific HP recommendation is intended. Customers should consult state and local requirements and regulations.
Electrical WITH THE POWER SWITCH IN THE OFF POSITION, POWER MAY STILL BE SUPPLIED TO THE PRINTER COMPONENTS. To completely cut power from the printer, you must unplug the power cord from the power outlet.
Ozone The high power UV light emitted by the curing lamps and ionizer bar reacts with oxygen and produces ozone. This formation tends to be greatest during lamp startup. The lamps include ozone filters to reduce ozone production. The printer should be operated in a well-ventilated area to avoid minor effects such as headaches, fatigue, and dryness of the upper respiratory tract. Normal air movement will mix the ozone with fresh air, causing it to revert back to oxygen.
Hazardous waste THE PRINTER ELECTRONICS ASSEMBLY CONTAINS A LITHIUM BATTERY DEVICE. THERE IS A DANGER OF EXPLOSION IF THE BATTERY IS INCORRECTLY REPLACED. The battery must be replaced only by authorized service providers, and must be replaced only with the same or equivalent type. Dispose of this lithium battery device in accordance with local, state (or province), and Federal (or country) solid waste requirements.

Print Mode Select the print mode whose settings you want to change.
Color Set Select the color set whose settings you want to change.
Change Print Mode Specific Settings Change settings for the print mode and color set you selected.
Select UV Lamp Power A high lamp power setting increases ink curing power, important at high speeds and for older lamps that are losing their intensity; a low setting for newer lamps extends their life.

Closing the shutter on the trailing lamp blocks the UV light from the lamp, which allows the drop of jetted ink to spread out more before it is cured, resulting in a glossier look to the print. The color profile used must take this into account for accurate color matching.

Select Print Delay A longer printing delay helps dissipate heat from heat-sensitive substrates, while a shorter delay speeds printing throughput.

12  Chapter 2 Configure and load media  ENWW

Work with the rigid media tables

Figure 2-1 Output (1) and input (2) tables

image28

The printer includes a set of standard input and output tables for rigid media handling: one for the input side of the printer, and one for the output side. These tables are assembled, installed and leveled when the printer is installed. The tables are designed to be used only when the tabletop is in the horizontal position and latched to the printer. The latches, see (1) Figure 2-2 Table latches and release cable on page 13, are needed for safety, print quality, and to provide a ground path to discharge the electrostatic charge from synthetic media.

The tabletop can be pivoted to a near-vertical position to save space during storage. After detaching the tables from the printer, release the tabletop latches by pulling the release cable, see (2) Figure 2-2 Table latches and release cable on page 13, under the tabletop. To return the tabletop to its operating position, pivot the table top down and press down firmly to engage the latches.

Figure 2-2 Table latches and release cable

image29

Optional extension tables are also available as accessories. When properly assembled and attached to the ends of the standard tables, the extension tables enable safe and reliable handling of large media sheets. During use, the extension tables must be latched to the standard tables for safety, print quality, and to provide a ground path to discharge the electrostatic charge from synthetic media. When not attached to the

ENWW  Work with the rigid media tables  13

standard tables, the extension table tops are designed to pivot into the storage position under their own weight.

image30

image31 CAUTION: The standard and accessory extension tables are intended for use only when attached to the printer as described in these instructions. When not in use, the tables should be stored with the table tops folded in the storage position. Use caution when operating the table tops and moving the tables, to avoid personal injury or damage to property.

image32image33 NOTE: If the accessory tables were properly leveled when they were installed, they should not have to be leveled again. If sheet-fed media feed problems occur, make sure the accessory tables are securely latched to the standard tables, and verify that the tables are level. Check for level over the fixed support assembly first, then over the folding support, and adjust the table wheels up or down as necessary.

image34image35

Load rigid media

image36

image37 NOTE:  See Table A-2 Media sizes on page 104 for a list of supported media sizes.

image38image39

1.If the rigid media tables are not already installed, position the input and output tables at each end of the media drive belt, and engage the attachment latches to the printer. Make sure that the pivoting table tops are securely latched in the operating position.

image40

image41 NOTE: If you have the optional roll-fed media accessory installed, remove the foam press rollers. The foam press rollers are not used with rigid media.

image42image43

2.At the end of the Configure Media process (see Configure media on page 11), press Yes on the control panel; or press Home > Load Media.

Before you can load, you must configure the media as explained in Configure media on page 11.

3.Select one of the following media rollers options, then press Proceed:
Flat Media If the rollers were set to “Yes” in the media configuration (see Configure media

on page 11), the rollers will move up or down as needed to be just above the surface of the media. If the rollers were set to “No”, the rollers will remain at their highest point and will not be used. In either case, the full imageable length of the sheet is available for printing.

Warped Media, Hold Down When a sheet is loaded, the leading edge is advanced so that it is underneath the output roller. Printing is allowed only until the trailing edge of the sheet has reached the input roller. The imageable area of the sheet is reduced by 65.4 cm (25.8 in) from both the leading and trailing edges.
Short Media Enables printing on sheets that are not long enough to reach the output roller and thickness sensor at the same time. The media length must be at least 22 cm (8.5 in).

image44

image45 NOTE: The media rollers are lowered to just above the media with any force or pressure, other than their own weight. They are designed to hold down lighter weight media with at most a moderate amount of warping. They may have no effect on heavier, badly warped media. For best results, use the flattest available media.

image46image47

4.Select the approximate thickness or enter the exact thickness of the media you are loading, then press Proceed.
5.Load the sheet of media onto the input table, sliding it forward against the media alignment bar (under the printhead carriage rail), then left along the media alignment bar until the media touches the leftmost alignment pin.

14  Chapter 2 Configure and load media  ENWW

6.Press Sheet Ready on the control panel, or Cancel to cancel the media load process.

image48

TIP: Before you press Sheet Ready, you can press Turn On Lamps on the control panel to initiate their warm-up cycle while you complete the subsequent steps in the load process. This will enable printing to begin sooner than if you allow the lamps to be turned on automatically. You can also change the head height at this time.

image49image50

7.Enter the number of sheets:
Single sheet
N-UP Sheet Feed (Same Dimensions) For two or more sheets of the same size loaded at once across the width of the printer
N-UP Sheet Feed (Different Dimensions) For two or more sheets of different sizes loaded at once across the width of the printer
8.Select the media length from the list, or enter a length manually, then press Proceed.

The printer measures the media, and the control panel displays a summary screen of the settings you specified.

9.Press Proceed to confirm that the media has loaded. The Home page appears.
10.Send a print job from the RIP or print a Stored Job from the printer.

For multiple copy jobs ejected to the output side of the printer, the printer control panel will prompt for the next sheet a short time before the previous sheet is done printing. Load the subsequent sheet against the media alignment bar, and press Sheet Ready on the control panel. The printer prints on the next sheet and will use the same option settings on all of the copies in the print job.

Use the camera to locate the sheets

The on-carriage camera is used to locate the position of each sheet as part of the load process. To specify load options:

1.On the Printing page, press Options.
2.From the Options menu, press Measure Media. The Measure Media Frequency menu appears:
Measure only on first load Only the first row is measured, and those measurements are used for all subsequent rows. Use the alignment pins to locate the sheets in subsequent rows. This speeds throughput by eliminating the measurement step for each row.
Measure on all loads Each sheet in every row of sheets will be measured, and reported to the server. This aids in accurate placement of edge-to-edge images. In this mode, use of the alignment pins is unnecessary.
Don’t measure media Does not measure the sheets, for fastest throughput. Use only if there are wide margins on all four sides, or for transparent media, which the printer cannot detect. Use the alignment pins to locate the sheets.

ENWW  Load rigid media  15

3.Press a Measure Media option.

When you select a Measure Media option, the Measure Media Type menu appears. This enables you to select a trade-off between image placement accuracy and throughput.

Minimal Measures the media width once, locates leading edge near the user side on subsequent loads.
Standard Measures the media width once, estimates skew by locating the leading edge near the user and service sides on subsequent loads.
One Edge On first load, measures both edges; on subsequent loads, measures the left edge only.
Maximal On every load, measures the media width at two points to estimate skew, finds the leading edge near the user side.

If the print job has wide margins, you can increase throughput with Minimal or One Edge. For edge-to-edge printing, increase accuracy by selecting Standard or Maximal.

4.Press a Measure Media Type option.

After you select a Measure Media Type option, a message appears to remind you to load the same number of sheets with every N-UP group, until they have all been printed. Press Proceed to dismiss this message and return to the printer options menu.

Quick Load

After printing is complete, you can reload a sheet of the same media type and dimensions without reconfiguring the media. Use Quick Load or Load:

image51

image52 NOTE: This option is available if you select Measure only on first load from the Measure Media Frequency menu (see Use the camera to locate the sheets on page 15).

image53image54

1.Press Load on the Home Page screen.

The control panel displays a menu with a Quick Load and Load option.

To load a sheet of media with the same media type with the same dimensions as the previous job, press Quick Load.
To load a sheet of media with the same media type with the same dimensions as the previous job, but different flatness, thickness, or number of N-UP sheets, press Load. The control panel allows you to respecify these options.
2.Place the media onto the media drive belt, and push it flush against the media alignment bar, then left along the media alignment bar until it touches the leftmost alignment pin.

At this point, the control panel allows you to adjust the vacuum fans and head height off the media.

3.Press Sheet Ready on the control panel.

Multiple-sheet N-Up allows you to print more than one copy of a single job or multiple jobs on multiple sheets across the belt of either the same or different dimensions, using multiple rows of sheets until the job is complete. Use the built-in media alignment pins for quick positioning of the sheets across the printer’s width. Align the left side of each sheet with one of the pins, with a small space from the right edge of the sheet to the next pin, to allow for variations in sheet dimensions. Alternatively, if you position the pins with zero clearance between the sheets and each pin, before each print be sure to raise the pins over the thickness of the sheets; otherwise the sheets could become skewed.

image56

image57 NOTE: When printing multi-sheet N-Up on media that cannot be detected by the printer’s media sensor (black, dark colored, reflective, or clear), the sheets in each row must be spaced equally.

image58image59

This type of printing works best with an image that has wide margins on all four edges, but edge-to-edge printing is also possible by carefully matching the dimensions of the image(s) to the dimensions of the media sheets. Margins can be defined by the RIP or can be set and adjusted on the printer.

To enable, select one of the N-Up Sheet Feed options when loading media and have the number of sheets you intend to print across the width of the printer in position to be loaded. Sheets must not be more than 7.6 cm (3 in) apart from each other. Use the alignment pins if you will be printing multiple rows.

Multi-sheet printing (same dimensions)

Multiple copies of a single image can be made by setting the quantity to a number equal to or greater than the number of the sheets you loaded. The printer prompts you to load more sheets until the number of copies you specified has been printed. You can print any number of copies in this configuration, even if the total number does not divide evenly into the number of sheets per row. Only the last row may have a different number of sheets.

The Multi-Image feature is enabled by selecting the Print 2-Sided / Multi Image N-Up button in the lower right corner of the Stored Jobs screen, then selecting Multi-Image N-Up in the following screen. Each of the jobs across the belt can be different jobs, but all jobs must have the same color set and resolution. Once the first job is selected, the printer displays jobs with a color set or resolution mismatch with a red border. If a different print mode is desired, or if separate jobs have different print modes but share the same resolution, a single print mode is changeable by selecting Print Mode in the summary screen. Enter the number of image groups or ‘rows’ to be printed and press Proceed.

Multi-sheet printing (different dimensions)

As with multi-sheet printing with the same dimensions, multiple copies of a single image can be made by setting the quantity to a number equal to or greater than the number of the sheets you loaded. Because

18  Chapter 2 Configure and load media  ENWW

sheets can be of different sizes, and the image of a single size, be careful about job alignment and overprinting onto the belt.

Again, as with multi-sheet printing with the same dimensions, the Multi-Image feature is selected from the Stored Jobs screen, following the same process. Because sheets can be of different sizes, and the images of various sizes, be careful about job size and alignment when selecting jobs.

Load roll-fed media with table-top roll holder

If the optional roll-fed media supply and takeup system with table-top roll holder is installed on the printer, you can print on roll-fed media in the following way.

image61

image62 NOTE:  See Table A-2 Media sizes on page 104 for a list of supported media sizes.

image63image64

1.If installed, detach the rigid media output table from the printer, and set it aside.
2.Install the table-top roll holders into the holes on the input table, allowing the media to be loaded centered on the printer.
3.Load media onto the table-top roll holder, spooling off the top, with the media centered.

image72 NOTE: Be sure to enter the correct media thickness. The printer can detect the thickness of sheet-fed media only if the media is loaded under the media thickness sensor, which is located at the user end of the carriage rail. For roll-fed media (if enabled), use the manufacturer’s specification or use a caliper to measure the thickness.

image73image74

5.As prompted by the control panel, ensure that only a single foam roller is being used and is in the storage position. Pull media from the spool and feed it into the printer, use the forward and backward buttons and fans on and off selector on the control panel to assist. Then press Proceed.
6.Place the foam roller into its operating position and advance the media past the output roller. Then press Proceed.
7.Return the foam roller to its storage position, ensure that the vacuum fans are off and hold the Advance Media button for several seconds to assist in media tracking. Press Proceed to continue.
8.Place the foam roller into the operating position and make any final positioning adjustments. Press Proceed.
9.On the Select Thickness Units screen, press the option that corresponds to the units you will use.

Available print modes

You select a print mode for each print job at the external RIP. Refer to the RIP documentation for instructions. Stored jobs can be printed in the mode originally specified by the RIP, or in any other mode at the same resolution as it was sent from the RIP.

The printer can print in several different modes for the combination of image quality and speed that you require. The modes are named after their intended applications. The higher-quality modes are meant for closer viewing. The faster modes are meant for viewing from longer distances. Maximum speeds shown in the table are for jobs with six colors, four colors, or four colors plus white spot printing. White flood fills print at approximately 45% the other color modes.

Stored jobs

When you send a print job to the printer, you can save the job automatically on the printer’s hard disk drive, on a rotating first-in-first-out (FIFO) basis. You can “lock” a job to prevent it from being rotated out, but this reduces the amount of space available for subsequent jobs to be saved. You can also save a stored job without printing it until you print it from the control panel, or only print the job without saving it.

The printer can store up to 96 sheet-fed or roll-fed jobs. These jobs are retained on the printer’s disk, even when the printer power is cycled on and off. When the number of stored jobs reaches the printer’s storage capacity, subsequent print jobs will be printed but not stored.

If a job is too large to be saved, it is simply discarded from memory after printing. If a complete print job has been received from the RIP and you cancel the print, it will still appear in the Stored Jobs listing.

Stored jobs can be viewed and managed from the control panel.

Thumbnail screen

To print or manage stored jobs, press Jobs on the Home or Printing page. On this page, you can view thumbnail images of the various jobs. Locked jobs (protected from automatic deletion) are identified by a padlock icon on the thumbnail image.

From the Stored Job thumbnails screen, you can perform these operations on the print job:

Press Set Filter to set a filter.
Press Multiple Select to select multiple jobs for a subsequent operation.
Press Information for the following kinds of information.
Press Max Sizes to view the total image area that can be stored at each combination of resolution and color set.
Press History to view a log of stored jobs activity.
Press Settings to specify how jobs are stored and printed. These settings are saved even when the printer is restarted.

28  Chapter 4 Printing jobs  ENWW

Press Job Storage Mode to choose whether jobs are printed and/or saved.
Print & Save Prints the job and saves it to disk.
Save Only Saves the job to disk without printing it. In this mode, the background color of the Stored Jobs section on the Home Page screen turns green.
Print Only Prints without saving the job to disk.
Press Job Storage Sorting to choose how jobs are sorted.
Press 2-Sided / Multi Image N-Up to set up a two-sided or multi-image N-Up print job using stored jobs. The printer prompts you to select the stored jobs that you want to use. All jobs must have the same color set and resolution.

When printing two-sided, side one of the sheet is ejected to the input side of the printer, and you are prompted to flip over and reload the sheet to print side two. After printing, the sheet is ejected to the output side of the printer.

image105

TIP: When printing a two-sided print job from the stored jobs on the printer, and the Auto Eject feature is disabled (set to “Off” under Printing page > Options > Eject Settings), Auto Eject is enabled or the printer prompts you to change the Print Position setting before printing proceeds. This is because double-sided printing by definition uses the Auto Eject feature. If necessary, you can print the sides as two single-sided jobs, turning the sheet over between sides.

image106image107

Properties screen

To view the properties of a Stored Job, or to print a Stored Job, press the job’s thumbnail image. From the

Stored Job properties screen, you can perform these operations on the print job:

To print the job, press Load & Print. The printer will prompt you for the number of copies to print. If you have multiple sheets loaded, each copy will print on a separate sheet, and the printer will prompt for additional sheets until the number of copies requested have been printed. You can print the job in any print mode that use the same resolution as the original job.
To adjust the right, left, leading, or trailing margins, press Margin Settings. The leading and trailing margins are applied to sheet-fed and roll-fed print jobs.
To change the print mode of a job, press Print Mode. You can only change the mode to one that uses the resolution at which the job was RIPed. To print the job at a different resolution, re-send the job from the RIP at the new resolution.
To delete the job, press Delete.
To lock or unlock the job, press the appropriate button. Locking a job prevents it from being deleted, but subtracts from the available memory for Stored Jobs.

image108

TIP: If you want to print on a media type that is different from the media specified in a Stored Job, or if you will re-linearize the printer, do not reprint the Stored Job. For the best color, re-send the job from the RIP instead.

image109

When printing a job, the printer checks that the currently loaded media matches the media type that was loaded when the job was stored. If different, a warning is raised. You can choose to not print the job, or ignore the warning and print anyway.

Printing on a media type or in a print mode that is different from the original job may result in a color shift.

ENWW  Stored jobs  29

TIP: While a print job is being received by the printer and saved to its internal hard disk (a process called “spooling,”) you can switch the UV lamps on or off as desired, rather than wait for the entire job to be spooled.

image110

Position and eject options

The sheet-fed printing option Position/Eject, on the Printer Options menu, enables you to control how images are positioned and whether the automatic sheet eject feature is enabled. By selecting Auto Eject Off, you can save media by combining print jobs that are smaller than the sheet size onto the same sheet, instead of on separate sheets. In this mode, you can print the jobs one after the other, or “nest” them across the width of the media in rows. Position/Eject is available when the printer is configured for sheet-fed media.

Position options For print jobs with a width that is less than the width of the media, you can control where the image is positioned (flush left, flush right, centered, or nested).
Eject options For sheet fed jobs, you can control whether the media is ejected after each job to the output side, input side, or not automatically ejected (Auto Eject Off).
Nested output When you set Eject to Auto Eject Off, and Position to Nested, the print jobs are nested onto the media until all jobs are printed or there is no more room on the sheet.

Printing tips

image112

image113 CAUTION: Synthetic media commonly used for inkjet printing can build up a static charge, especially in environments with low relative humidity. This charge can pose an electrostatic discharge (ESD) hazard to persons, the printer, and other equipment. It can be safely discharged by draping a grounded chain or tinsel over the top of the media, or by wiping the media with a solution of 90% isopropyl alcohol and allowing it to dry for five minutes before printing. A relative humidity of 40%-60% will greatly reduce problems with static electricity.

image114

30  Chapter 4 Printing jobs  ENWW

Rigid cut-sheet media Use only flat, unwarped, undamaged sheets, with parallel opposite edges and 90° corners. For optimal image quality, use smooth-surfaced media. Images printed on porous media will lack fine detail.
Curing continues for 24-48 hours The UV ink will continue to cure for a day or two after printing. Maximum durability and adhesion is achieved when the ink is fully cured.
If you print on the media drive belt, clean the ink off the belt as soon as possible. The longer that ink remains on the belt, the more difficult it is to remove. To remove ink from the belt, moisten the ink with isopropyl alcohol, let stand for a few minutes, and wipe with a paper towel. Carefully remove any flaked ink from the area.
To avoid printing on the media drive belt when printing edge-to-edge (0 margin) jobs, you can affix dark-colored masking tape on the belt where the sides of the media will be. Remove or replace the tape periodically as ink accumulates on the tape.
Do not attempt to adjust the vacuum level for the printheads. It has been factory adjusted for best performance.
Printing on reflective media will reflect UV light onto the printheads, which will cure the ink over time and clog the ink jets. To minimize this:
Do not keep reflective media loaded on the printer when not in use.
Perform a manual purge after printing on reflective media.
Visually inspect the printheads via the service door for ink buildup or ink curing, If observed, clean the printheads (see Clean the printheads on page 79).
To load reflective media, the General Media Setting Visible to Printer should be set to Visible.
To reduce printing artifacts when printing on Corrugated Plastic (Coroplast) or Polystyrene (Sintra) sheets, try creating a custom media type with the lamps set to Low, Low. Note that this setting could reduce the gloss of the print.

5image115Use white ink

With the white ink option available from HP, you can replace the light magenta and light cyan inks with white ink, resulting in four colors of ink plus white ink. This enables you to print with white ink using various techniques.

Printing with white ink may require special preparation of the image to be printed or special setup in the RIP.

Refer to the documentation provided with the application software and RIP for step-by-step procedures.

White ink option overview

White ink printing is available as an option that can be delivered with a new printer or as a field upgrade to an existing printer. If the option is delivered with a new printer, it is installed with the new printer. In the case of a field upgrade, the option is designed to be installed either by a service technician or by the customer operator.

The white ink option consists of two parts (see instructions that accompany the kit for detailed instructions):

White ink option upgrade A one-time process that upgrades the printer to a white-ink capable printer
White ink conversion Replaces the existing light cyan and light magenta inks in the printer with white ink.

Refer to the White Ink Upgrade Kit Installation Instructions, HP part number CQ11490006, included in the white ink upgrade accessory kit, for detailed instructions for the upgrade and conversion.

Types of white ink printing

Many different design effects can be achieved with white ink that would not be possible otherwise, especially when printing on dark, colored, metallic, or clear media. There are three basic design techniques for printing with white ink:

Under-fill A solid rectangle (or irregular shape) of printed white ink that is cured, then a color image is printed on top of it. When used on a non-white, transparent, or reflective surface, this can provide better color saturation or allow colors that are similar to the media color to be visible.
Over-fill A color image is printed and cured, a solid rectangle (or irregular shape) of white ink is printed on top of it. This is most often printed on clear media to create a sign that is viewed on a light box (for example, a shopping mall map, airport advertisement, or bus stop signage). When viewed from the opposite side of the media on which it was printed, the image must be reversed (mirrored) in the RIP or application software before printing.
Spot color Any white shape (including text) that is cured with and in the same plane as the rest of the artwork, rather than in a separate plane or layer. In conventional (analog) offset or screen printing, this might be called a “knockout,” because none of the colors are overprinted.

image116

image117 NOTE: When printing a CMYK or CMYKcm image without a white under-fill on non-white media, color saturation may be reduced, depending on the color of the media used.

image118image119

White ink maintenance

HP White Ink Homogenizer White inks used in wide-format printing have pigments that have a tendency to settle over time. The printer’s white ink option incorporates a vibrating homogenizer base that keeps the white ink pigments in suspension without operator intervention.
Printhead The automatic printhead servicing (purging and wiping) must be supplemented with manual printhead cleaning, to enable optimal print quality.
Shelf life The white ink has a maximum shelf life of six months from date of manufacture. Replace the white ink after the Warranty Ends date printed on the box.

7Sleep/Wake mode Sleep unloads the media, powers down the UV lamps, ionizer bar, printheads, carriage, ink pumps, and media drive motors, but maintains vacuum to the printheads to prevent ink leakage. The fans over the service station also continue to run. Wake powers up the printer components. The printer goes into sleep mode automatically after a user-defined period of time, and “wakes” automatically when a print job is received or a printer operation is performed from the control panel.

NOTE: If printhead vacuum is ever lost, the ink in the printheads will seep onto the service station. (Vacuum loss will not result in additional ink being drawn out of the ink supply boxes.)

To prevent ink leakage during an unexpected power outage, use the vacuum system’s 24 volt auxiliary power supply and connect it to an uninterruptable power supply (UPS). See Appendix A for specifications. It is not necessary to connect the entire printer to a UPS, only the vacuum system needs to be connected to avoid ink seepage.

Attention messages

The printer issues an Attention message to inform you of a condition that needs your attention. There are three types of Attention messages:

Actions An error condition that stopped printing or will prevent printing from starting. You must correct the error before the printer will be ready to print. The Attention icon blinks between yellow and red when the message is new. After you read the message, the icon turns red.
Warnings A condition that, if left unaddressed, could result in substandard prints or a condition that will require an action before printing can continue. Any action on your part is optional. The Attention icon blinks between yellow and red when the message is new, After you read the message, the Attention icon turns into the Ready icon unless an Action message is present.

Printing Options menu

Print Position and Eject Direction This menu option controls two related functions that enable you to control how print jobs are positioned on sheet-fed media, and how to eject the sheets:
Print Position When the printed image does not span the entire width of the media, positions the printed image flush left (nearest the control panel or user side), flush right, centered, or nested on the media (if Auto Eject Off is selected).
Eject Direction You can choose whether the media is ejected to the output or input side after each job prints, or disable automatic eject.

See Position and eject options on page 30 for further details.

Space Between Prints (roll-fed) Sets the blank space between print jobs, between 025 cm (010 in).
Measure Media (sheet-fed) For cut-sheet media, you can choose various levels of precision for finding the left (user-end), right (service-end), and front edges of the media.

First select a measurement frequency (trade-off between precision and speed):

Measure only on first load Measure only once, after you configure the media; best for fast throughput when precise image placement is not required or when using the media alignment pins
Measure on all loads Best for precise image placement, such as for N-UP and edge-to-edge printing
Don’t measure media Best for fast throughput when precise image placement is not required and there are very wide margins around the image

Then select a measurement type:

Minimal Measures the width of the media once and finds the front right edge; no skew detection. Choose Minimal for fastest throughput.
Standard Measures the width of the media once, and finds the front edge in two places to estimate skew
One Edge (available when Measure on all loads is selected) Measures the user- and service-end edges on the first sheet, user-end edge only on subsequent sheets, and the front right edge (no skew detection). For single-sheet jobs only, not available for multi-sheet N-UP. Works best on jobs with wider margins.
Maximal Measures the width of the media in two places to estimate skew. Choose Maximal for greatest precision and skew detection when printing edge-to-edge.
Measure media (roll-fed) For roll-fed media, you can choose various levels of precision for finding the left (user end), and right (service end) edges of the media.

38  Chapter 6 Use the control panel  ENWW

When loading Locates the left and right edges only when loading a roll of media.
Before each copy Locates the left and right edges of the media before each print. This enables the printer to compensate for any “drifting” of the media, and print the image at the correct location.
Use Ionizer Bar Sets whether to use the ionizer bar to reduce the electrostatic charge on synthetic medias (the default setting is on or enabled). You may want to disable the ionizer in humid environments where electrostatic charge is not present on the media, or to reduce the wear on the ionizer’s discharge electrodes. The ionizer bar is powered on only during media load, printing, and when the lamps are on.
Use Thickness Sensor Sets whether to use the automatic media thickness sensor, or to prompt you to manually enter the thickness.
Head Height off Media Automatically raises the rail to set the printhead clearance from the media, at the height you specify. A lower height reduces overspray, but increases the chances for a head strike on the media. Bidi calibration is automatically adjusted for changes in this value.
Print White Space Provides the option of causing the printer to advance the media past unprinted space in the document file without the usual “printing” carriage motion. The printer will finish curing any printed areas before skipping this space. This option increases the printer’s effective speed (throughput).
Quality Check When enabled, prevents printing from occurring if more than a certain number of missing or misfiring jets are not replaced by working jets. You can specify whether the printer asks you whether to stop printing with a Warning message, or if printing stops automatically without a Warning.
Increase UV Lamp Power When the printer is no longer fully curing the ink on prints, use this option to incrementally increase the lamp power. If the power needs to be increased again, create a custom media and set the UV Lamp Power to Medium or High, or replace the bulbs (the bulbs should be replaced in pairs). In this case, the printer will warn you that the print may not fully cure until the bulbs are replaced. (Printing Page > Options > Increase UV Lamp Power)
Unidirectional Print Direction
Use Fast Print Speed Enables faster printing when using Indoor Signage Plus and Indoor Signage print modes. It is set to Yes by default, but you can turn it off by selecting No.

AutoJet

AutoJet detects individual inkjets that are misfiring or not firing at all. During subsequent printing, the printer compensates for these jets by using other jets in their place, ensuring maximum print quality without reducing print speed.

You can also identify and map missing jets manually from the Manual Calibrations menu (see Manual Jet Mapping on page 55). You may want to manually map weak or misdirected jets that AutoJet does not detect and substitute.

Jet replacement is not available in Express mode.

To run AutoJet:

Select AutoJet Calibration from the Auto Calibrations menu (see Automatic calibrations on page 51), or

image176

TIP: AutoJet does not work with transparent media, nor with many translucent media. In this case, run Manual Jet Mapping, or map jets on opaque media before loading transparent/translucent media for printing.

image177image178

1.Press Calibrate from the Printing page, then press Auto Calibrations > AutoJet Calibration in the menu.
2.The printer prints the AutoJet test pattern.
3.The printer reads the AutoJet test pattern and maps any missing jets to available working jets. The control panel shows the progress of this operation as the percentage completed.
4.The printer prints an AutoJet report.

50  Chapter 7 Calibrate the printer  ENWW

image179image180 NOTE: The AutoJet calibration requires that the printheads are in correct alignment. If AutoJet maps out a large number of jets even though there are no obvious jetting problems, the printhead Y calibration (a factory calibration) may need to be performed again. In this case, contact HP or your authorized service provider.

image181image182

Automatic calibrations

The printer’s piezo printheads are aligned by the installer. Head and bidirectional calibrations should be necessary only rarely (for example, when the heads have been moved within the carriage or replaced).

1.Press Calibrate from the Printing page, then press Auto Calibrations in the menu.
2.Select one of the Auto Calibrations.
AutoBiDi (bidirectional) Calibration Ensures that every working jet fires at precisely the same location (regardless of the carriage direction of travel).
Auto Head X (head-to-head) Calibration Ensures that the printheads are in alignment relative to each other.
AutoJet Calibration Locates and substitutes missing jets for working jets (see AutoJet on page 50).
Full AutoSet Runs all three calibrations in sequence. The printer prints a test pattern then reads it and makes the necessary adjustments or jet substitutions. After completing the calibrations, a report is printed that shows:
Calibration results A summary such as SUCCESSFUL CALIBRATION or an error message
Header showing the date and time, software version, and printer type
Calibration detail The calibration data for each head. The AutoJet detail reports how many jets were mapped out by AutoJet, how many are permanently mapped out by the operator, and whether the head is usable (from a jetout standpoint) in the various print modes. The higher quality modes use jet replacement, so they can print successfully with a greater number of jets out than Billboard mode.
AutoSet Summary When enabled, a table of the results of the Full AutoSet calibration is printed after the AutoSet test patterns. When you enable the AutoSet Summary, you can show or hide the detailed calibration data.

Manual calibrations

When you run the calibrations from this menu, you evaluate the calibration test patterns visually and enter the calibration values via the control panel.

Press Calibrate from the Printing page, then press Manual Calibrations in the menu. The Manual Calibration menu consists of these options:
Media Feed Calibration Calibrates the media advance accuracy for band-free printing. Visual and (for rigid media only) camera-assisted calibrations are available.
Manual BiDi Registration The manual version of AutoBiDi Calibration.
Printhead X Calibration The manual version of Auto Head X Calibration.
Manual Jet Mapping The manual version of AutoJet.

ENWW  Automatic calibrations  51

Jet Status Lines Print a quick test pattern to see which jets are out.
Default Registration Data Sets all registration data to zero.

After calibration and jet mapping, perform a linearization or color calibration (as supported by the RIP).

See Linearization on page 58.

image183

image184 NOTE: The manual BiDi and X head calibrations are time-consuming and can be error-prone, but is necessary when calibrating transparent media or other media that the printer’s digital image sensor cannot calibrate.

image185image186

Media Feed Calibration

This calibration allows you to calibrate the accuracy of the media advance. Inaccurate media advance can result in blank spaces between print swaths (too much advance) or overlapping swaths (too little advance).

1.On the Manual Calibrations menu, press Media Feed.
2.Select the calibration method and press Proceed. Depending on the loaded media, some options may not be displayed.

990 mm (39 in) calibration Sheet fed only, uses the printer’s onboard image sensor for precise adjustments. If the media feed needs larger adjustments, use the ruler-measured calibrations first. Use for maximum accuracy.

510 mm (20 in) calibration Sheet fed only, uses the printer’s onboard image sensor for precise adjustments. If the media feed needs larger adjustments, use the ruler-measured calibrations first. Use to conserve media.

900 mm (34 in) calibration Prints a 900 mm (34 in) test pattern so you can verify its length with an accurate metal ruler. Cut the pattern from the media web, then measure and adjust the media advance as needed until the pattern is exactly 900 mm (34 in) long.

250 mm (10 in) calibration Prints a 250 mm (10 in) test pattern so you can verify its length with an accurate metal ruler. This is not as precise as the 900 mm (34 in) calibration, but it uses less media. Measure and adjust the media advance as needed until the pattern is exactly 250 mm (10 in) long.

The image-sensor based calibration (sheet-fed media only) prints a reference pattern, ejects the media, and prompts you to rotate and reload the media so the pattern can be measured. To account for the slight variability in the media feed mechanism, repeat these calibrations three to five times to obtain the best calibration. The software allows you to position the patterns anywhere on the sheet so you can print multiple iterations on the same sheet.

Input MFN Enter the Media Feed Number that was displayed after a previous media feed calibration, to return to that setting without performing the calibration again.

image187

TIP: To achieve the best results from the ruler-measurement calibrations: Use a good-quality ruler with accurate marks. Use a ruler that is in the same units as the pattern selected. (Do not attempt to use a metric ruler to read an English-units pattern or vice-versa.) Use a ruler that is at least as long as the pattern you are measuring. (Do not attempt to add up shorter ruler measurements to achieve the total length of the pattern.)

image188

To avoid ruler issues, use the image-sensor based calibration.

Manual BiDi Registration

Bidirectional registration is a method to align each of the printheads so that dot placement is accurate in both directions along the X axis (along the direction of printhead travel).

The bidirectional registration pattern consists of a series of vertical lines. Half the pixels in this pattern are printed in one direction, half of them in the other direction. When the pixels are accurately aligned, the pattern is clear. When the dots are not aligned, the pattern appears fuzzy and ill-defined.

image191

image192 NOTE: AutoBiDi Calibration is the automatic version of this calibration. Try AutoBiDi first before running this manual calibration (see Automatic calibrations on page 51).

image193image194

1.Press Calibrate on the Printing page, then press Manual Calibrations in the menu.
2.Press Manual Bidi Registration to proceed. The control panel displays this prompt: Print a manual bidi registration page?
3.Press Yes.

The control panel displays controls that enable you to position the registration pattern on the media. This enables you to feed the same sheet of media into the printer multiple times without overprinting previous patterns. For best quality when printing on rigid sheet-fed media, position the pattern approximately 20 cm (8 in) from the edge.

4.Use the control panel controls to position the pattern, then press Proceed.

The printer prints the registration pattern, then prompts you to advance the media so you can inspect it.

ENWW  Manual calibrations  53

5.Advance the media by pressing Move Belt Forward, then press Proceed. The control panel displays this prompt:

Bidi registration Head 1: 0

6.Examine the BiDi Registration pattern for the current head, and determine which pattern is the closest to perfectly aligned.

Use a printer’s loupe (10X magnification or higher) to select the pattern, since the lines in the patterns may be difficult to see.

7.Press the or control panel keys repeatedly until the number next to the pattern that is closest to aligned perfectly is displayed.

For example, if pattern +2.0 is the closest aligned, press Proceed to change the display to: Bidi registration Head 1: +2

If a printhead is extremely out of alignment, there may be no pattern in alignment. Since the vertical bars are nominally five pixels apart, you can add +10 or -10 to a pattern number to shift the colored bars right or left by one black bar. Alternatively, you can perform the BiDi Registration repeatedly, which will move the head in smaller increments, until the head is aligned.

8.Press the button.

The control panel message increments the head number by one.

9.Repeat steps 4 through 6 for each of the heads.

When you have entered registration values for all heads, the control panel displays this message: Registration Successful

Printhead X Calibration

Precise positioning of each drop of ink is essential for optimal print quality. This is possible only if you register all printheads in the printhead assembly to each other in the X (along the length of the platen) direction.

This is a two-part process:

Print a registration pattern.
Enter the X registration data for each head.

image197image198

1.Press Calibrate from the Printing page, then press Manual Calibrations in the menu.
2.Press Printhead X Calibration in the menu.

The control panel asks whether you want to print a manual head-to-head calibration page.

If you need to print a new calibration pattern, press Proceed. The printer prints a calibration page. When the calibration page has printed, the control panel displays this prompt:

54  Chapter 7 Calibrate the printer  ENWW

Take readings from left side of pattern.

If you have a calibration pattern from a recent print, you can use it to calibrate the heads. Press Cancel and go to the next step. (For best results, do not use a previously-printed pattern, print a new pattern.)
2.Press Proceed.

The control panel displays this message: X Direction Registration Head 2: +0

3.Examine the X direction pattern (in the left-hand group of patterns) for the current head, and determine which pattern of colored and black lines are the closest to perfectly aligned.

Use a printer’s loupe or magnifying glass (10x magnification or higher) if the patterns are difficult to see.

4.Press the or control panel keys repeatedly until the number next to the pattern that is closest to aligned perfectly is displayed.

For example, if pattern -1 is the closest aligned, press the button to change the display to: X Direction Registration Head 2: -1

If a printhead is extremely out of alignment, there may be no pattern in alignment. Since the black vertical bars are five pixels apart, you can add +5 or -5 to a pattern number to shift the colored bars up or down by one black bar. Alternatively, you can repeatedly perform the X calibration, which will move the head in smaller increments, until the head is aligned.

5.Press Proceed.

The control panel message increments the head number by one.

6.Repeat steps 4 through 6 for each of the heads.

When you have entered registration values for all of the patterns, the control panel displays this message:

Registration successful.

Manual Jet Mapping

Jets that are missing or misfiring are usually detected by the AutoJet calibration. Alternatively, you can map out jets manually using the Manual Jet Mapping function. You may want to manually map weak or misdirected jets that AutoJet does not substitute.

image199

TIP:  AutoJet is the automatic version of this calibration (see AutoJet on page 50).

image200

TIP: For best results, print the prime bars and purge the printheads as necessary to ensure the maximum number of working jets. See Ink page on page 41 for instructions.

This option enables you to reset bidi registration, head-to-head registration, or jet mapping data, or any combination of them. After running this option, the deleted calibration values must be reestablished by running the calibrations.

Unfixed Jets Report

The Unfixed Jets Report displays a table showing, for each print mode, which colors are printing with non-working inkjets that are not being automatically replaced with working jets by AutoJet mapping (“unfixed” inkjets). For each combination of ink color and print mode, “No” means there are no unfixed jets, “Yes” means there are unfixed jets.

Linearization

As the density of an image varies from highlights to shadows, or from lighter to darker tints, the printer should accurately reproduce these areas in a predictable, or linear, fashion. The process of linearization (or color calibration) involves printing and reading color test patches, and calibrating the printer to ensure that the expected and printed densities will match. This in turn will ensure optimal color matching.

Color calibration is a feature of the RIP connected to the printer. Refer to the documentation that accompanies the RIP for further information.

How to print selective gloss

Sselective gloss is a special application that shows both gloss and matte effects in the same print.

This section describes a method that can extend the profitability and versatility of your printer. Its application is at your own risk.

Only operators technically experienced with the RIP and the printer are recommended to try it. If in doubt, contact your local printer service provider.

1.You must create gloss and matte media profiles for the material that is going to be used. Depending on the media absorption and print mode, the gloss result may vary. For this reason, it is your responsibility to check print results in advance with different configurations (print mode and media).

During the creation of the matte and glossy profiles, it is important to uncheck the Detectable setting.

Creating a gloss media type requires closing the shutter of the trailing lamp. As the trailing lamp will be off, there will be a delay between printing and curing (polymerization), which allows the drop of ink to expand, and thus to create the glossy effect.

2.From the control panel’s Home screen, press the Media icon.

image203

3.Press Configure.

image204

60  Chapter 8 Specialty printing options  ENWW

4.Press Create Media Type.

image205

5.As mentioned in the following screens, the new media type must be created from a standard one. It is important to choose the proper media in order to have the correct settings. So, it is highly recommended to create a gloss media profile for all the different substrates you would like to use for this purpose.

image206

image207 CAUTION: Incorrect media settings may directly affect printer performance and print quality, and create risky situations such as printhead crashes.

image208

ENWW  How to print selective gloss  61

6.Enter the media name. In this example, a new gloss mode is created from a standard Foam Board.

8.Press Change Print Mode Specific Settings.

image211

62  Chapter 8 Specialty printing options  ENWW

9.Check the option Shutter Trailing Lamp for all print modes.

image212

10.Press Change General Media Settings to uncheck the Detectable setting for matte and glossy.

image213

11.Save the changes.

image214

12.Repeat for other media types that you intend to use.

ENWW  How to print selective gloss  63

Follow a similar procedure to create matte media profiles; but, in this case, uncheck Shutter Trailing Lamp for all print modes.

Hardware procedure

1.Select your matte media profile.
2.Load the media at the 0 position.
3.Select the job and print.

image215

4.Select your gloss media profile.
5.Reload the media at the same 0 position.
6.Select the second job and print.

image216

Be careful to use the same width, length, and position every time. And load carefully for proper alignment. Multi-sheet printing is not recommended; single-sheet printing is preferred for the best alignment between different loads.

How to print relief texture

This section describes a method that can extend the profitability and versatility of your printer. Its application is at your own risk.

Only operators technically experienced with the RIP and the printer are recommended to try it. If in doubt, contact your local printer service provider.

64  Chapter 8 Specialty printing options  ENWW

There are two ways to print relief texture:

Print a background image and then print the texture on top of it.
Print the texture on colored media.

The following example shows the creation of wallpaper with relief texture.

image217

1.Create two files: one with the background image (if needed), and the other with the texture.
2.Texture is achieved by changing the linearization curves and ink limit of the media profile. The basis is the same for every RIP, but the details may vary. Procedures for Caldera and Onyx RIP software are described below.

Caldera RIP

1.Select your texture file from the image bar and drop it onto your printer driver.

ENWW  How to print relief texture  65

2.Click the color settings icon.

image218

3.Go to the Output tab and the linearization curves section. Click the button to edit.

image219

66  Chapter 8 Specialty printing options  ENWW

4.You will now see the current linearization curve of your selected media profile. In order to create the relief effect, you must alter the four primary colors (CMYK). To do so, click the up-arrow icon about five times and change the ink limit to 400% in order to reach an acceptable level of relief. Or you can drag each point to the level you need.

image220

image221 NOTE: The linearization curves field is now set as Untitled.ppc. This is the modified curve. You can save it by clicking Save if the level of relief is satisfactory.

image222image223

5.When you have finished, press OK, close the color settings window, and print.

Once you have completed your texture job, remember to load the original linearization curves back if you want to print normally. To do this, click the Reset button in the Output tab.

image224

TIP: You can have two different configurations of your current printer driver settings and easily swap between the background and the texture mode. To do so, in the main printer driver window, save your texture settings as a new preset.

Substitute cleaning procedures for air quality regulatory compliance

The various Air Quality Management Districts in California may have rules that restrict the use of cleaning solvents containing Volatile Organic Compounds (VOCs). This document provides alternative cleaning procedures for printers located in the areas of California where the use of solvents containing VOCs is restricted. These revised procedures supersede any previous instructions, guidelines, or recommendations issued by HP regarding the cleaning or maintenance of the relevant printers in California. Maintenance procedures that do not involve the use of VOCs for cleaning are not affected.

Printers located in California should not be cleaned using SolaChrome-UV Printhead Flush, HP UV Printhead Flush (HP product number CH122A) or isopropyl alcohol (IPA) unless other VOC compliance measures are in place. This includes the use of any product samples which came with the printer when it was purchased. Dispose of any remaining Printhead Flush in accordance with applicable regulations.

The compliant alternative liquid for cleaning and maintaining this printer is: Methyl Acetate (CAS# 79-20-9), at least 98% pure, undiluted.

Follow these safety guidelines when handling parts and cleaning chemicals:

When handling parts and cleaning liquids use appropriate personal protective equipment (PPE) as prescribed in the Material Safety Data Sheet (MSDS). This includes the use of safety goggles, chemical protective gloves, and other protective personal clothing. Additional useful information may also be provided on websites operated by the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health.
Only those components originally designated for cleaning with Printhead Flush or IPA should be cleaned with the alternative cleaning liquid.
Methyl Acetate is a flammable liquid; read and adhere to the instructions in the MSDS document for safe handling and storage. State and local agencies or fire departments may impose additional requirements.
Follow all health, safety and environmental protection regulations when using any solvents to clean or maintain the printer. An agency that administers health and safety regulations within the State of California is the Department of Industrial Regulations, Division of Occupational Safety and Health (Cal-OSHA).
Minimize the quantity of cleaning liquid used during maintenance to avoid spills, contamination, or harm to printer parts. Carefully moisten cleaning cloths or swabs with the cleaning liquid, and ensure

76  Chapter 10 User cleaning  ENWW

that none of it drips onto the printer. Any excess or residual liquid should be removed by cleaning the area with a dry cloth. Failure to clean off any residual cleaning liquid could cause damage to the printer, or could adversely affect the printer’s level of image quality.

Disposal of waste must be in accordance with applicable regulations.

ink system vacuum is removed. If the printer standby power switch is switched off, but

the power cord is not removed, power to the vacuum is preserved. The ink system

vacuum maintains the negative pressure required for printing operation and prevents

ink dripping from the printheads when the printer is idle.

You can preserve power to the ink system vacuum during power outages by connecting

the supplied power cord (length: 137 cm (4.5 ft)) from the auxiliary power connection

(below the ink box racks) to one of the following:

Wall outlet 100240 VAC, 50/60 Hz, provides temporary power to the vacuum

system when it is necessary to remove power from the printer for service.

Troubleshooting checklist

Before you troubleshoot your printer, make sure that it is properly installed as described in Introduction on page 1.

Follow the steps in this checklist to isolate and resolve printing problems.

1.Does the printer’s power come on?

YES: Go to question 2. NO: Check the following:

The power cable may not be plugged into an electrical outlet.
If the printer is plugged into a surge protector, the surge protector may not be connected to power, or it may be switched off.
The circuit into which the printer is connected may be switched off at the circuit breaker.
2.Did the start-up sequence of the control panel end by displaying the Home Page screen similar to the one shown in Home page on page 35?

YES: Go to question 3. NO: Check the following:

There may be a hardware problem with the printer’s internal components. Follow the diagnostic routine on the control panel to determine the problem. Write down any error codes and call technical services as directed by the control panel.
3.Can you send a file from the RIP to the printer? YES: Go to question 4. NO: Check the following:
The network cables may not be securely connected to the RIP computer, printer, and network switch or wall outlet. Check the cable connections and try again.
4.Can you send (print or download) a document from a client computer to the server? YES: Go to question 5. NO: Check the following:
The connection from the client to the local area network may not be configured correctly. See your system administrator for assistance.
The Ethernet cable between your computer or network and the RIP computer may not be securely connected at both ends.
Your computer may not be working properly. Run an application that you know works correctly and print to be sure.
The computer’s port may not be working properly. Print to another output device that you know works correctly (and is not connected to the RIP) to check this.
5.Is the print quality good?

YES: Then the problem is not covered in this checklist. Contact Technical Services. NO: Check the following:

Banding or general poor image quality The printheads may need to be calibrated (see Calibrate the printer on page 49). One or more inkjets may be clogged or not firing (see Ink page

ENWW  Troubleshooting checklist  109

on page 41). The media advance may need to be recalibrated (see Media Feed Calibration on page 52).

Inaccurate color or under- or over-saturated output the wrong color profile may be selected at the RIP. Refer to the documentation that accompanies the RIP.
Inaccurate color or lack of detail one or more inkjets may be clogged or not firing (see Ink page on page 41).

Since automatic head maintenance cannot occur when the printer is powered down, keep the printer powered on at all times if possible. If automatic head maintenance does not occur for an extended period, manual purging may be necessary to restore the printheads to working condition.

Noisy carriage motion or repeating print artifacts Noisy carriage motion can be eliminated by cleaning (see Clean and lubricate rail strips on page 77 or Clean the carriage wheels on page 84). If the carriage wheels develop flat spots due to non-use, use the Carriage Motion Troubleshooter to restore their shape (from the System page of the control panel, see Tools > User Diagnostics> Carriage Motion).
Media buckling or media feed problems the wrong media could be selected in the Media Wizard (see Configure media on page 11). The media may not have been loaded squarely (see Configure and load media on page 10).
Head strike if the printhead is striking the media, check how the media is tracking from the supply spindle. The sides of the media should be parallel to the sides of the printer, with no wrinkling or buckling. If necessary, reload the media. See Load rigid media on page 14 for instructions. Also check the Media Wizard to see whether the correct media is selected (see Configure media on page 11).

Warranty claims

The printer is covered by a manufacturer’s limited warranty, which includes the printheads.

Startup and check jet health

This section shows you how to configure your printer for best quality printing.

Start with the printer in good working order

These techniques will be much less likely to work if you are not using a printer that is in good working order:

The printer was properly installed by an HP-authorized service technician, in a facility and environment that meets HP specifications as published in the Site Preparation Guide.
The printer has the latest version of the embedded software (firmware) installed.
The printer hardware is working, and has been properly maintained as outlined during operator training.
The printheads are calibrated (bidirectional, head-to-head, head height, printhead X calibration); see Calibrate the printer on page 49 for instructions.
The media feed is calibrated with the media on which you will be printing. See Media Feed Calibration on page 52 for instructions.
There is sufficient ink installed and available for resupply. The Warranty Ends date marked on the ink packaging has not passed.
The number of service hours for the leading and trailing lamps are within 20% of each other. If one lamp has significantly more hours than the other lamp, the appearance of prints may change unexpectedly, To correct this, the lamps can be exchanged with each other or replaced.
The external RIP is installed and communicating with the printer, and the operator is familiar with its use.
Avoid touching the media during printing.

Load media correctly

Follow these guidelines when loading media:

Use only media that is clean, flat, and undamaged.
Keep the printer’s environment within the specifications published in the Site Preparation Guide. In particular, an environment with a relative humidity below 40% can result in high levels of static electricity, while a relative humidity above 60% can cause some medias to absorb moisture and develop an uneven (non-flat) shape or curl. Both conditions can cause printing problems.
In low-humidity environments, use static charge abatement measures when handling synthetic media (vinyl banner, plastic boards), such as grounded copper tinsel, isopropyl wipes, or anitstatic spray.
Select the Media Wizard settings that match the media you will use. The Media Wizard entry you select may not be named with the exact media name, but one that has similar characteristics allowing use of the same Media Wizard settings (including vacuum fans, lamp intensity and swath delay). If possible, select a default Media Wizard set that has been tested and validated; these are indicated by an asterisk

(*). All other Media Wizard entries are user-generated and can be modified when needed.

Configure and load media as described in Configure media on page 11.
Wipe down synthetic media with IPA before printing to reduce static charge, and remove fingerprints and dust, which could become visible in the print.

Check jet health

At the beginning of the day’s printing, verify that all of the inkjets are either firing or have been substituted by another working jet.

1.Load media, then press Check Jet Health on the control panel’s Ink page.
2.Run a Purge & Wipe.

From the control panel’s Ink page, press Purge.

3.Print the Check Jet Health pattern again.
4.Compare the print with the previous day’s (or most recent good) Prime Bars print.
If today’s Check Jet Health print is comparable to the previous day’s print, you may want to verify jet replacement by pressing Check Jet Health from the Ink page. If all jets are working or replaced, you are ready to select printer settings.
If today’s Check Jet Health print shows noticeably more broken or missing lines than the previous day’s print, run the AutoJet calibration (from the Printing page, press Calibrate, then select Auto Calibrations > AutoJet Calibration from the menu). Then run a Check Jet Health pattern once or twice until the missing lines have printed or are replaced.

If the Check Jet Health pattern does not improve after performing these steps two or three times, or if a large number of adjacent jets cannot be recovered, one of the following may be necessary:

Inkjets may need to be manually mapped out (Printing page > Calibrate > Manual Calibrations > Manual Jet Mapping)
Printheads may be damaged
Service station may need to be calibrated
Contact your service representative for further assistance.

RIP settings

For detailed operating instructions, refer to the RIP user guide.

Choose a resolution

The print resolution is determined by the print mode (see Table 4-1 FB550 print modes and maximum print speeds on page 26). There is no resolution setting on the printer.

For most images, use a 600×600 dpi print mode.
If a grainy image is acceptable (when viewed from a longer distance or as a draft, for example) and faster print speeds are desired, use a 600×300 dpi print mode.
For more saturated colors or printing on clear or backlit media, use a 1200 × 600 dpi print mode.

Choose a color profile

Select the profile that matches the media name, or most closely matches the material, you are using.
For accurate color matching, perform a color calibration (linearization) at least once for each media.

Color matching

The accuracy of color reproduction by the printer is the result of the interaction of numerous factors, listed below. Correction of errors in color reproduction may involve adjustments in more than one of these factors.

Installation and initial calibrations (performed by an authorized service technician)
Head height
Printheads Y calibration
BiDi calibration
Printhead X calibration
Ongoing maintenance (performed by the operator) Clogged or misfiring jets caused by lack of regular cleaning
Ink Settling of pigments, ink that is past its Warranty Ends date, bad batch
Color sets and print modes Printing with different color sets (six or four colors plus white), and different print modes
RIP issues Linearization, color profiling, different methods for using light cyan and light magenta, settings such as Grey Color Removal (GCR)
Profile matching Match the color profile used by the RIP to create the RIP file with the print mode (see Available print modes on page 26) used to print the image.
