ENWW 1

Operating requirements

Electrical

Make sure the line voltage meets the requirements. See

●

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/pressure assembly to either of two options:

◦

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 spe cifications.

●

Optimal printing occurs within these ranges. See The high power UV light emitted by the curing lamps reacts with oxygen and produces ozone. This

●

formation tends to be greatest during lamp start-up. The printer should be operated in a wellventilated 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.

Specifications on page 92 for details.

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.

Specifications on page 91 for details.

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 print server (RIP) with the included 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.

●

2 Chapter 1 Getting started ENWW

Connect the RIP

The printer receives print jobs from a raster image processor (RIP), from either HP or a supported thirdparty manufacturer.

To connect the printer to the HP RIP Software, refer to its User Guide for detailed instructions.

●

To connect the printer to a third-party RIP, follow this procedure:

●

Install the VideoNet cable

1. Power off the computer you will be using to run the RIP.

2. Connect the printer to the RIP comput er 's Ethernet port using the included cab le. NOTE: The included cable is 7.62 m (25 ft) in length. If necessary, you can use a crossover

Category 5 (or higher) 10/100Base-T cable , u p to 38 .1 m (12 5 ft ) in le ng th .

3. Connect the user workstation(s) to the RIP.

You can connect your workstation to the RIP via a local area network or directly using a single cable.

To connect to the print server via a network hub, use a standard straight-through Category 5,

●

10/100Base-T cable. To connect a single workstation to the RIP without a network, use a Category 5, 10/100Ba se-

●

T crossover cable, such as the VideoNet cable, part number 0582323.

4. Turn on the computer power.

Install the VideoNet protocol

The following procedure is for Microsoft Windo w s Vista (32–bit). Other operating system versions are not supported.

1. Open Network Connections by clicking the Start button > Control Panel > Network and Internet >

Network and Sharing Center > Manage Network Connections.

2. Right-click the local area connection that corresponds to the VideoNet card, then click Properties.

(Type the password or provide confirmation if prompted.)

3. Click Install.

4. In the Select Network Feature Type dialog box, click Protocol, and then click Add.

5. Browse to the folder on the hard drive or HP softwa re disc th a t co nta i ns t he Vide oNet protocol

(videonet.inf).

6. Follow the prompts to complete the installation of the VideoNet protocol.

It can be difficult to determine which icon represen ts which connection. One way to determine this is to unplug the VideoNet cable and observe which icon shows a red “X”.

To avoid confusion in the future, rename the VideoNet icon to “VideoNet.”

ENWW Connect the RIP 3

Install the RIP software

Install and configure the RIP software as outlined in the documentation supplied with it.

▲

Install a language file

The printer's control panel interface optionally can be switched b etween English and one other language. To install this option, refer to the instructions provided with the second language software files. These files can be downloaded from the HP Graphic Arts web site at

http://www.hp.com/go/graphic-arts.

Important operating notes

UV CURE INK IS PERISHABLE. Unlike other inks used in wide format printing, UV cure ink has a

●

limited shelf life. Plan to rotate your ink stock and use it promptly by the date printed on the ink box.

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 lamp s sh ou ld b e sw itch ed off only via the printer software.

The maximum diameter allowed on the optional takeup spool is 178 mm (7.0 in) on a 76 mm (3 in)

●

core. The supply-takeup system can support rolls of up to approximately 56.7 kg (125 lb). The media supply may be wound either printed-side-ou t or printed-side-in, but the optional takeup,

●

if used, must be loaded printed-side-in. The default head height set to 2.159 mm (0.085 in) above the media. (The space below the carriage

●

will measure 1.778 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 (Printer Settings > Head Height Off Media).

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.

Enable AutoTune during long periods of unattended printing on roll-fed media. AutoTune runs

●

AutoJet at user-defined intervals to ensure that all jets are either working or substituted with working jets.

Wear cotton gloves when loading media to prevent fin gerprints that co uld show after printing. You

●

can use isopropyl alcohol (IPA) to clean fingerprints and reduce static electricity on synthetic medi a. 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 ca use 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 th e printer.

●

ENWW Important operating notes 5

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 operate d 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 prin ted 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.

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 lamp s re act s with oxyg e n a nd pro d uce s

●

ozone. This formation tends to be greatest durin g lamp start-up. The printer sh ould be operated i n a well-ventilated area to avoid minor effects such as headaches, fatigue, and dr yness of the upp er 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. Disp ose of this lithiu m battery device in accordance with local, state (or province), and Federal (or country) solid waste requirements.

Workflow overview

When the printer is connected to the HP RIP Softwa re, here is how a typical print job progresses from the client workstation to the printer. If you are using a non-HP RIP, refer to the documentation that accompanies it for details.

1. The operator sends a file to be printed from a client workstation.

2. The print job is received by the print server.

Once it reaches the print server, the print job may be reprioritized, combined with other jobs, rerouted, or otherwise manipulated. Refer to the print server online help or manual for instructions.

3. The print server RIPs the job.

The raster image processing (RIP) process translates the PostScript language data th at comprises the print job into the data required by the printer.

4. The server sends the image to the printer for printing.

In most cases, the printer’s automated jet maintenance makes manual jet recovery unnecessary, even after the printer has been idle overnight. Banding in printed output may in dicate cl ogged jets or the need for calibration.

Since automatic head maintenance cannot occur when the printer is powered down, ke ep th e 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.

Specifications on page 92 for information on using the included auxiliary power supply for the

See vacuum/pressure system.

The printer will automatically enter a Sleep mode when it has been idle for a user-defined period of time (see

Front Page on page 37 for details).

Special features

Printheads

Printheads — variable drop size, piezoelectric printheads.

●

Ink system

Off-Head System (OHS) — bulk ink boxes with integrated filters. No-drip quick connectors simplify

●

ink box replacement. Onboard vacuum/pressure (VP) system — provides vacuum to maintain negative printhead

●

pressure, and air pressure to purge the printheads or ink tubes without removing them from the printer.

Patent-pending automated printhead service station — fully maintains the hea lth of the printheads

●

while idle or in service, without operator intervention.

Media handling

Automatic head height — automatic head height adjustment and patent-pending shuttered UV

●

lamp system allow the printer to accept rigid sheet-fed media up to 6.35 cm (2.5 in) thick. Automatic media width sensing — automaticall y detects the width and position of the media loade d,

●

for precise image placement.

●

Calibration

The Advanced Automation Eye uses a high-resolution d igital imaging sensor (camera), photodiode, and embedded software to align the printheads, detect and replace missing jets, linearize output, and characterize media (with supported RIP).

●

Built-in static charge abatement — ionizer bars help dissipate static electric charge from synthetic media.

AutoEdge — automatically aids the loading of rigid sheets by detecting the leading edge.

AutoSet calibration — automatically aligns printheads bidirectionally for precise positi oning of inkjet pixels, and runs AutoJet.

AutoJet calibration— compensates for lost or misfiring jets by locating them and using substitute jets without slowing printing speed.

Roll-feed AutoTune scheduling — runs AutoJet at user-de fined intervals, for highest quality during unattended roll-fed printing. Optionally, if unsubstituted non-working jets are found, printing stops until the problem is corrected.

Automatic color calibration — linearizes output over the entire density range (with RIP support). Color profiling — creates custom color profile s for third-party media (with RIP support).

Configure printing

The printer can print in several different modes for the combination of quality, resolution , and speed that you require.

The resolution is determined by the resolution at which the job was rasterized by the external RIP. The Print Mode is selectable at the control panel. The actual print speed is determined by the combination of output quality, print length and width, and printing delay selected at the control panel (described below).

Table 2-1 Typical print speeds by mode

Jet replacement refers to the printer’s ability to locate and replace inkjets that are clogged or misfiring. High Quality mode has the best jet replacement, Billboard Quality mode has the highest speed, but without jet replacement.

The current print mode is shown in the top center of the control panel. To change the print mode, follow these instructions.

1. On the control panel, press the Print Mode key.

The print mode menu appears, with these options:

Billboard Quality

●

Production Quality

●

High Quality

●

2. Press a print mode to select it.

A menu appears with these options:

Bidirectional

●

Unidirectional - Print From User (1) to Service (2) Side (prints only when the carriage is moving

●

away from the control panel) Unidirectional - Print From Service (2) to User (1) Side (prints only when the carriage is moving

●

toward the control panel)

14 Chapter 2 Printing ENWW

The printer can print in both directions (bidirectional) or in one direction only (unidirectional). Unidirectional printing can occur in either direction. Printing occurs at about half the speed of the corresponding bidirectional print mode. Unidirectional printing eliminates the bidirectional misalignment that occurs when printing on media that is not perfectly flat.

3. Press a direction option to select it.

In Production and High Quality modes, a menu appears with these options:

Normal — prints at full speed.

●

Plus — provides reduced horizontal gloss banding when printing bidirectionally in large image

●

areas or solid colors. Normal Fine Text — prints at half the normal head speed to improve the output quality of fine

●

text and line art by eliminating overspray. Plus Fine Text — provides reduced gloss banding and improved fine text and line art.

●

Sharp Edge — improves the appearance at the ed ges of larger text, colored borders, graphics,

●

and images by directing the inkjet overspray into the printed area. This mode requires an additional print pass than Normal mode. (Not available with unidirectional printing or in Billboard or Plus mode.)

CAUTION: Printing in Fine Text mode, which prints at 50% of the speed of the "normal"

Production and High Quality modes, may expose the media to excessive heat from the UV lamps, which could result in bowing of the center of the media, and possible contact with the printheads. Thinner rigid media such as fluted polypropylene (Coroplast) are susceptible. To avoid warping, set a media delay in Printer Settings > Printing Delay, or in a custom Media Wizard parameter set for Fine Text printing.

This could also be an issue with Sharp Edge and Plus mode printing, although these modes print at 80% speed, so they are less susceptible to excessive heat buildup.

4. Press an option to select it.

The media settings screen appears.

5. Press the Media Settings button under any of the resolutions in the table to change the settings

for that resolution.

ENWW Configure printing 15

A menu appears that enables you to change any of the se settings:

Printing Delay

●

Lamp Mode

●

Shutter Aperture

●

These settings are explained in the following sections.

NOTE: You can change the settings for a standard media type temporarily. To save the changes

permanently, copy the standard media type into a new media type, and save its settings.

6. To set a printing delay, press the Printing Delay option in the Media Settings menu.

The Printing Delay screen appears. Increase the printing delay to allow more heat to dissipate fro m the media between print passes. Decrease the delay to increase throughput.

7. Increase or decrease the delay by pressing the ▲ or ▼ keys.

8. Press Proceed (►) to save your changes, or Cancel to discard them.

9. To set the lamp mode, press the Lamp Mode option in the Media Settings menu.

The Lamp Mode screen appears.

10. Configure the UV lamps operation by touching the option for the leading and trailing lamps. Buttons

will appear or disappear to present only valid combinatio ns (for example, you cannot set both lamps to Shuttered).

For standard media listed in the Media Wizard, leave the la mp settings at their default values,

●

then adjust as needed. Faster print modes require higher lamp settings to ensure sufficient curing.

●

If the ink is not curing, increase the setting. The lamps will gradually lose curing effectiveness,

●

so increasing the setting eventually may become necessary. If the media is wrinkling or warping from the heat of the lamps, lower the setting.

●

11. To set the aperture settings, press the Shutter Aperture option in the Media Settings menu.

The aperture settings screen appears.

12. Adjust the shutter apertures, or press Proceed (►) to continue.

You can select the aperture (opening amount) for each shutter, and/or completely close one of the shutters, during printing. This enables you to reduce the warping of rigid media by reducing the amount of light and heat emitted by the lamps. The aperture can also be set by touching the UV lamps info panel.

The UV lamp shutters are vertical when completely opened, and rotate to cha nge the aperture. An aperture setting of 0 degrees is completely open; 20 degrees is half open, “Closed” is completely closed. You cannot set both shutters to closed while printing. During printing, the lamp icons on the control panel are dynamically shaded to indicate the aperture setting. The icons will change as the carriage direction changes if the leading and trailing aperture settings are different from each other.

13. Press Proceed (►) to save the settings and return to the Front Page, or Cancel to restore the

previous print mode settings.

16 Chapter 2 Printing ENWW

Equivalent print modes

From the standpoint of UV curing and temperature, all print modes fall into one of five print speed groups: A, B, C, D, or E. If you change the Printing Delay, Lamp Mode, or Shutter Aperture for any print mode, the changes apply to all print modes within that group.

Configure media

Before the printer will accept a print job, it must be configured for a specific media type. The currentlyconfigured media type, if any, is displayed in the upper left corner of the control panel.

1. If the control panel displays the media type you intend to print, press the Load key an d go to and print on rigid media on page 21. Otherwise, continue to the next step.

2. From the Front Page screen, press the Configure key.

The Select Media to Load menu appears. The list of media ends with the option Create Media

Type.

TIP: Start by using one of the standard media types. If you are not using a standard media type,

select the standard media type that most closely mat che s th e me dia you are using. Then only if necessary, create a new media type using the standard type yo u selected a s a starting poin t, and adjust it as needed.

3. Press a media name, or Create Media Type.

If you pressed a media name, a list of settings appears.

CAUTION: The input and output tables are rated at a maximum load of 56.7 kg (125 lb). Do not

exceed this maximum load.

NOTE: The printer senses the weight of the media before printing begins. If a heavy board is

detected while the printer is set to Light, the printer automatically switches to the Heavy setting. This cannot be changed during printing. Printing in Heavy mode is slower than in Light mode due to the slower belt and carriage speeds, bu t re duce s the ch ance of da mag e to the med ia belt d rive motor.

Load and print on rigid media

NOTE: The minimum length of rigid media that can be loaded and pr inted by the printer is 33 cm (13

in).

1. At the end of the Configure Media process (see Configure media on page 19), press the

Proceed key on the control panel: OR

from the Front Page screen, press the Load Media key. Before you can load, you must configure the media as explained in

2. On the control panel menu, press one of the following media rollers options:

Flat Media — if the rollers were set to “Yes” in the media configuration (see

●

media on page 19), 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 imageab le length of the sheet i s availa ble 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 (25.76 in) from both the leading and trailing edges.

Short Media — enables printing on sheets that are not long enough to rea ch th e outp ut roller

and thickness sensor at the same time. The media length can be less than 33 cm (13 in) but at least 11 cm (4 in).

NOTE: The media rollers are not lowered onto 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.

3. On the control panel, enter the approximate thickness of the media you are loading.

4. Load the sheet of media onto the input table, sliding it forward against the media alignment bar

(under the printhead carriage rail), then left a long the media a lignment bar until the med ia touches the media fence.

5. Press the Sheet Ready foot pedal or button on the control panel, or Cancel to cancel the media

load process. At this point you can also adjust the vacuum fans in each zone, and th e printhead height clearance

from the media. If the sheet is warped or not being held down, you may want to increase the vacuum or raise the head height. A lower head height reduces overspray, but increases the chance of the carriage or printheads striking the media.

TIP: To begin printing faster, initiate the UV lamps startup cycle by pressing the Turn On

Lamps key on the control panel Front Page screen.

Multi-sheet N-UP

Multi-sheet N-UP allows you to print a multiple-copy job on multiple sheets across the belt, and multiple rows of sheets, until the job is complete.

22 Chapter 2 Printing ENWW

To print multi-sheet N-UP, load multiple sheets on the printer, then send a print job from the RIP with a quantity greater than or equal to the number of sheets you loaded. The printer will prompt you to load more sheets until the number of copies you specified has been printed. You can a lso print Sto red Jobs as multi-sheet N-UP (see

This type of printing works best with an image that has wid e margins on all four edges, but edge-to-edge printing is also possible with the appropriate printer settings, and by carefully matchin g the dime nsions of the image to the dimensions of the media sheets.

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

1. On the Front Page screen, press the Settings key.

2. From the Settings menu, press the Measure Media option.

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 shee ts 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

subsequent loads. Standard — measures the media width once, estimates skew by locating the leading edge

●

near the user rand service sides on subsequent loads. One Edge — measures the media width once, locates the left edge on subsequent loads.

●

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 thro ughput with Minimal or One Edg e. For edgeto-edge printing, increase accuracy by selecting Standard or Maximal.

4. Press a Measure Media Type option.

After you select a Measure Media Type option, the Printer Settings menu reappears.

“Incomplete” rows

You can print any number of copies in a multi-sheet N-UP job, 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.

For example: in a twenty-sheet job, you might be able to fit three sheets in each row, so yo u might print six rows of three sheets, plus one row of two sheets (6x3=18, 1x2=2, 18+2=20). If th e last row is a partial row, load the sheets from the user end toward the service end.

Stored jobs

When you send a print job to the printer, you ca n 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 ro ta te d 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 i t from the control panel, or only print the job without saving it.

The printer can store up to ten sheet-fed or roll-fed jobs, with a total area of approximately 2.5 x 2.5 m (98.4 x 98.4 in). 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 ten, su bsequent 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 pause or cancel the print, it will still appear in the Stored Jobs listing.

Stored Jobs can be viewed and managed from the control panel. The Front Page screen shows the stored jobs mode and the number of jobs stored and locked (protected from automatic deletion).

To print or manage Stored Jobs, press the Jobs key on the Front Page screen. This screen shows a thumbnail image of up to ten stored jobs, and four function buttons. Locked jobs are identified by a padlock icon on the thumbnail image.

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

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.

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 no t print the jo b, or ignore the warning and print anyway. Printing on a media type that is different from the original media may result in a color shift.

Load ink

The amount of ink in the ink supply box is tracked by the printer software and recorded on its corresponding profiler. The control panel displays a bar graph with the ink levels in each ink box. When the control panel shows that the ink is low, replace the ink box with a full ink box of th e same color, and replace the profiler.

NOTE: You may want to wear gloves (latex or nitrile) and have a paper towel handy to catch the drop s

of ink that may fall from the ink tube connection during this procedure.

Unload an empty ink box

1. Remove the profiler.

2. Lift the box out of its holder and turn the box upside down so the ink tube is pointing up.

3. Grasp the metal connector where the ink tube enters the printer, and push it up to release the ink

supply tube.

4. Remove and dispose of the ink box (refer to the MSDS for proper disposal procedures).

Load a full ink box

1. Open the new ink box and locate the supply connector.

2. Locate and remove the profiler, and set aside until step 5.

3. Vigorously shake the ink box for one minute, invert and install the ink bo x into position in the holder,

so the ink supply tube is at the bottom of the box.

NOTE: The pigments in the inks settle to the bottom of the ink box during storage. To avoid

inaccurate color in prints, invert and vigorously shake the ink bo x fo r at least one minute before installing it into the printer.

4. Insert the ink tube connector into the metal connector on the printer.

The position for each ink color is shown on a label below each ink box and next to the profiler docking station.

5. Install the profiler in the corresponding docking station slot.

10. Sleep/Wake mode — Sleep 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. 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.

To prevent ink leakage during an unexpected power outage, use the vacuum/pressure 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/pressure system needs to be connected to avoid ink seepage.

11. Print prime bars — fires all jets by drawing a set of lines called prime bars. This is a good way to

inspect and prepare the jets for printing after they have been idle (see You can also print a similar pattern called Print Jet-Out Lines, which shows which jets have been detected and replaced by AutoJet (see

27. Attention messages — blinks on the control panel when the printer detects an error condition,

potential error condition, or when you make a change that requires recalibration or othe r actio n to ensure best print quality.

The ATTN (Attention) key blinks on the control panel when the printer detects an error condition, potential error condition, or when you make a change that suggests recalibration or other action to ensure best print quality. There are two types of ATT N messages:

Actions — the printer has detected 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. Warnings — the printer has detected 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. Printing is not interrupted for a Warning message.

When the printer issues one of these messages, the ATTN key will blink. Press the ATTN key to display a list of message titles, and select a title to display a detailed cause-and-recovery screen.

If you choose to not correct a Warning condition and resume printing, the ATTN key will remain displayed, but will not blink until the printer issues a new Warning or Action message. The messages can be dismissed by correcting the condition, or by pressing the applicable key on the detail screen.

TIP: The ATTN key is displayed in Novice Mode. To disable the ATTN key, switch to Expert Mode.

Expert mode routes most messages to an Actions & Warnings menu option. In this case, it is your responsibility to monitor these messages via the menu, since the ATTN key will not appear. See

*Margins:

●

Right and Left Margin — sets the amount of blank space fo r the right and left margins, between

◦

6-127 mm (0.25–5 in) for roll-fed media, and between 0-127 mm (0–5 in) for rigid cut-sheet media.

AutoTune on page 52 for instructions.

Leading Margin — defines the margin on the leading edge of cut-sheet media, betwee n 0-38

◦

cm (0–15 in). Trailing Margin — defines the margins on the trailing edge of cut-sheet media, between 0-38

◦

cm (0–15 in). Overprint — the distance beyond the edge of the media to print, to help avoid a blank strip if

◦

the sheet is slightly skewed, not perfectly rectangular, or other error is present. You can specify a separate value for the left and right margins, and leading and trailing edges.

NOTE: If you load roll-fed media after printing on cut-sheet media, the printer automatically resets the

margins to 6 mm (0.25 in). You can still change them at any time.

TIP: You can position an image anywhere on the media by setting the right margin (horizontal or x

distance from the right edge) and leading margin (vertical or y distance from the leading edge). Since the image appears upside down as it emerges from the printer, the upper left corner of the image will appear at this point.

Space Between Prints (roll-fed) — sets the blank space between print jobs, between 0–25 cm (0–

●

10 in). 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), fl ush right, or centered on the media.

44 Chapter 3 Control panel ENWW

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, the printer prompts you to select a measurement frequency (trade-off between precision and speed):

Measure only on first load — measure only once, after you co nf igu re the m edi a; best for fast

◦

throughput when precise image placement is not required or when using the media alig nment 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

After you select one of these options, the printer prompts you to select a measurement type:

Minimal — measures the width of the media once and finds the front right edge; no skew

◦

detection Standard — measures the width of the media once, and finds th e front e dg e in two places to

◦

estimate skew One Edge — 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 d etection). 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 Minimal for fastest throughput, 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.

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.

Print White Space — provides the option of causing the printer to advance the media past white

●

space in the document file without the usual “printing” carriage motion. The printer will finish curing any printed areas before skipping white space. Skipping the white space increases the printer's effective speed.

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.

Purge Type — sets the purge type used when the Purge key is pressed from the Front Page screen,

●

Standard or Performance. Performance is more effective, but uses more ink compared to Standard. Eject Sheets to Input Side (sheetfed) — after printing, reverses the media feed and ejects the

●

printed sheet out the input side. This makes it possible for the operator to perform all operations on the input side of the printer, and makes the wo rkflow for two-sided printing more efficient. (Twosided printing of Stored Jobs always ejects out the output side. See details.)

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 jet s in th eir pla ce , e ns uring maximu m print quality without reducing print speed.

You can also identify and map missing jets manually from the Manual Calibrations menu (see

Jet Mapping on page 58). You may want to manually map weak or misdirected jets that AutoJet does

not detect and substitute. Jet replacement is not available in Billboard mode. To run AutoJet:

Select AutoJet Calibration from the Auto Calibrations menu (see

AutoTune

AutoTune runs AutoJet maintenance automatically at intervals you specify. You can use the Quality Check Mode feature to handle AutoJet errors (with or without user intervention). AutoTune is shown on the menu only when roll-fed media is loaded.

1. On the Front Page screen, Calibrate key, then press AutoTune on the menu.

The control panel displays the AutoTune status (off or current interval).

2. Press ▲ or ▼ to set the AutoTune interval.

3. Press the Proceed (►) key.

NOTE: When AutoTune is enabled, it will be executed as scheduled regardless of whether you initiate

it manually from the control panel.

Quality Check

When you run AutoJet manually, the software notifies you if there ar e any jet or align ment problems so that they can be addressed. When AutoTune runs AutoJet at scheduled intervals, you can use the Quality Check feature to handle AutoJet errors.

When Quality Check is enabled, if any missing jets are found that are not substituted by a working jet, or if the BiDi calibration has not been performed, the operator can be alerted by the control panel or the job can be routed to the Attention queue on the HP RIP Software.

1. On the Front Page screen, press the Settings key, then press Quality Check from the menu.

52 Chapter 4 Calibration ENWW

Auto 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 b een moved within the ca rriage or replaced).

The automatic calibrations apply X offsets (in the direction of carriage motion) to individual jets. The manual calibrations apply X offsets to the entire printhead. Because of this, the automatic calibrations are much more precise and yield better print quality than the manual calibrations.

1. Press the Calibrate key from the Front Page screen, 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). AutoH2H (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. This is the same

●

calibration performed as when you press the AutoJet button on the Front Page screen (see

AutoJet on page 51).

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 var io u s p rint modes. The higher quality modes (Production and High Qual ity) use jet replacement, so they can print successfully with a greater number of jets out than can 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.

ENWW Auto calibrations 53

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 the Calibrate key from the Front Page screen, 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 AutoH2H Calibration.

●

Manual Jet Mapping — the manual version of AutoJet.

●

Print Jet-Out Lines — prints a version of the Prime Bars in which missing jets that are replaced

●

are marked with a black square. 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

NOTE: The manual BiDi and X head calibrations are time-consuming and can be error-prone, but is

necessary when calibrating transparent media or othe r me dia th at the printer’s digital image sensor cannot calibrate.

Linearization on page 63.

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 (to o lit t le advance). The Media Wizard stores this value by media type, and displays a media feed number (MFN), which you can record for subsequent entry.

The media feed number enables you to quickly specify a known good media feed setting without recalibration. For example, you could keep a list of med ia fe e d n umber s by me dia t ype , o r by me dia type and full, half, and nearly empty supply rolls.

1. On the Manual Calibrations menu, highlight Media Feed.

2. Press the Menu In key to select the option.

You can calibrate the media feed using the printer's image sensor or a metal ruler. The imagesensor based calibrations (sheet-fed media only) print a reference pattern, eject the media, and prompt 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 cal ibrations three to five times to obtain the best calibration. The software allows you to position the patterns anywhere on the she et so you can print multiple iterations on the same sheet. The ruler-based calibrations are recommended only for gross adjustments before using the image sensor.

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.

54 Chapter 4 Calibration ENWW

510 mm (20 in) calibration — sheet fed only, uses the printer's onboard image sensor for precise adjustments. If the media feed needs larger adjustme nts, 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.

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.

Figure 4-1 Media feed calibration pattern

TIP: To avoid cutting the 250 mm (10 in) pattern from the media web, copy the marks from the printed

pattern to the long edge of a letter-size (or A4) sh eet of paper. Then measure the transferred marks and adjust the media advance as needed until the marks are exactly 250 mm (10 in) apart.

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 carriage 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.

62 Chapter 4 Calibration ENWW

Linearization

As the density of an image varies from highlights to shadows, or from lighter tints 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.

You should perform a color calibration when:

You notice a shift (change) in color output

●

Changing media types

●

Changing print mode (only if the most precise color matching is required)

●

You are about to begin a long run of many copies of the same print

●

You are about to print a job that you may have to print again at some point in the future and match

●

the original color

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

For maximum accuracy, the photodiode must be cooled by its fan before reading color patches. The control panel displays a countdown timer while the photodiode is being cooled by the fans.

ENWW Schedule of tasks 67

Clean and oil rail carriage-wheel strips (bi-weekly)

Ink dust and debris can accumulate on the carriage-wheel strips. These particles become obstacles and friction for the carriage wheels, which can appear as repeating output anomalies on the printed media.

1. Clean the three carriage-wheel strips well with Isopropyl alcohol.

2. Lubricate the top carriage-wheel strip from end to end on the rail (moving the carriage to clean the

full length of the rail). The included oiled rags can be reused until there is no clear surface remaining on the rag (rags

should be replaced quarterly). Clean these surfaces weekly or more frequently, d epe nding on th e amount of debris in the environment.

CAUTION: Do not add additional oil to the lubrication cloths. The cloths are created to distribu te

a very thin film of oil. If too much oil is deposited, oil pockets can cause friction with the carriage wheels, which will produce output anomalies.

3. Lubricate behind the top area of the rail where the carriage wheels contact.

68 Chapter 5 User cleaning ENWW

4. Lubricate the lower carriage-wheel strip from end to end on the rail (moving the carriage to clean

the full length of the rail).

NOTE: Even if the oiled cloth appears clean, it should be d iscarded quarterly so that the oil doe s

not become sticky.

ENWW Clean and oil rail carriage-wheel strips (bi-weekly) 69

Clean the rail encoder strip (bi-weekly)

Ink dust and debris can accumulate on the encoder strip and block accurate reading of the encoder marks by the carriage encoder reader.

1. Using a lint-free cloth moistened with IPA (Isopropyl alcohol), wipe the top and bottom of the

encoder strip, cleaning the entire length of strip. Use common rubbing alcohol, which is 70% isopropyl alcohol and 30% water.

2. After cleaning most of the encoder strip, move the carriage to clean the re mainder of the encoder

strip.

70 Chapter 5 User cleaning ENWW

Manually clean the printheads (bi-weekly)

1. Move the output-side table away from the printer.

2. From the control panel, select the following:

Tools > Maintenance > Manually Clean Printheads

This will cause the rail and output roller to raise to their highest positions and move the carriage out over the belt.

3. Open the output-side door to access the carriage. CAUTION: Wear protective gloves, such as latex, to protect you r hand s from being stain ed wi th

ink.

CAUTION: Wear safety glasses to protect your eyes from ink and head flush tha t may splash

into your eyes.

4. Place a piece of scrap vinyl under the carriage (see A in the photo below). You can use any media

that will protect the belt from dripping ink and/or head flush.

5. Fully saturate a lint-free cloth with head flush solution.

ENWW Manually clean the printheads (bi-weekly) 71

6. For each printhead, use a single finger on a clean area of the saturated lint-free cloth to wipe the

printhead orifice from the input-side to the output-side of the carriage. To avoid pushing debris into the printhead orifice, make sure each wip e is done with a clean area

of the cloth. The cloth should be fully saturated with head flush.

7. From the control panel, select PURGE.
