2 Printer status
Check printer status
You can check the current status of the printer in the following ways:
The HP Internal Print Server displays the status of the printer, the loaded substrate and the ink
system. The latest alerts are summarized at the bottom of the main window (see Printer alerts
●
The front panel displays the ink levels by default; otherwise, you can see the ink levels by selecting
●
the the Ink System icon
the front panel.
. In addition, the most important current alert, if any, is displayed in
Printer alerts
The printer can communicate two types of alerts:
Errors: When the printer is unable to print.
●
●
Warnings: When the printer needs attention for an adjustment, such as a calibration, preventive
maintenance or ink cartridge replacement.
Printer alerts appear primarily at the HP Internal Print Server, but one alert at a time also appears at the
front panel.
HP Internal Print Server: A summary list of alerts appears at the bottom left of the main window.
To display a more complete and detailed list, select Information > Alerts.
●
Front-panel display: The front panel shows only one alert at a time, which is judged to be the
most important. It generally requires the user to press the OK key for confirmation, but in the case
of a warning, it disappears after a while. Some alerts reappear when the printer is idle and there
is nothing more important to report.

3 Printer calibration
Align the printheads
Precise alignment between printheads is essential for color accuracy, smooth color transitions and sharp
edges in graphical elements.
To align the printheads, go to the HP Internal Print Server and select Printer > Printhead alignment.
You can select automatic or manual alignment; the HP Internal Print Server will recommend one or the
other, but you can always choose.
Automatic alignment is a fully automated procedure that ensures optimal print quality in most cases.
The printer prints some patterns and scans them with the built-in line sensor. This is the
recommended method for any smooth, high-quality substrates (including vinyl, banners or backlit).
If the printheads have many defective nozzles, automatic alignment may not give good results.
●
●
The procedure takes about 14 minutes and consumes 9 inches of substrate.
Manual alignment provides reasonable print quality when automatic alignment is not possible,
typically because a highly-textured or non-white substrate is loaded (mesh, perforated, some
fabrics, transparent, colored). The printer prints 8 series of patterns, and you must choose the best
result from each of the series (for example, number 10 in the picture below).
The procedure takes about 15 minutes and consumes 9 inches of substrate.

Chapter 3 Printer calibration
ENWW
Troubleshoot printhead alignment
Automatic printhead alignment may fail occasionally. In some cases, you may see the front panel error
message "Automatic Printhead Alignment is cancelled because of scanning errors". In other cases,
there is no error message but the print quality is not satisfactory. Here are some possible explanations.
There is some problem with substrate advance (see Substrate-advance compensation
on page 7). After fixing any substrate-advance issue, retry automatic printhead alignment.
●
●
●
●
You are using a highly-textured (some banners), non-white or very reflective (some satinated
offset) substrate. Please use manual printhead alignment in these cases.
The substrate is wrinkled. Check that the substrate is correctly loaded with uniform tension. If
necessary, try adjusting substrate parameters such as tension or drying and curing temperatures.
The substrate is not wide enough. Repeat the alignment process using a substrate roll at least 24
inches (610 mm) wide.
The printer window was open during the printhead alignment process.
●
●
If the problem persists, please try using manual printhead alignment, or call your service representative
Printhead alignment diagnostic plot
The printer offers a printhead alignment diagnostic plot, to assess the quality of the current printhead
alignment. To print it, start the HP Internal Print Server and select Printer > Printhead alignment >
Diagnostics plot.
1. The colored crosses on the left side of the plot should show the lines well aligned with each other.
2. The vertical lines to left of center should be straight, without kinks.
3. Of the four vertical lines at the top right of the plot, the leftmost two should be straight, without kinks.
Substrate-advance compensation
Accurate substrate advance is important to print quality because it is part of controlling the proper
placement of dots on the substrate. If the substrate is not advanced the proper distance between
printhead passes, light or dark bands appear on the print, and there may be an increase in graininess.
The printer has a substrate-advance sensor and is calibrated to advance correctly with all the substrates
appearing in the front panel. When you select the type of loaded substrate, the printer adjusts the rate
at which to advance the substrate while printing. However, if you are using a custom substrate or not
satisfied with the default calibration of your substrate, you may wish to change the substrate-advance
substrate-advance compensation will solve your issue.
ENWW
Substrate-advance compensation
7
You can view and change the substrate-advance compensation of the currently loaded substrate at any
time from the HP Internal Print Server by selecting the print job and then the Printing Adj. button, or by
selecting Printer > Printing adjustments.
If you prefer the print quality after changing the figure in the Advance field, press the Apply button, and
thereafter your preferred substrate-advance compensation will always be used for that particular
substrate type.
The substrate-advance sensor may not work correctly if it is dirty. See Clean the substrate-advance
NOTE: Some substrates are invisible to the substrate-advance sensor; in which case, the sensor will
not work and should be turned off. You can turn it off by using the Automatic Tracking (OMAS) field in
the Loaded Substrate window of the HP Internal Print Server. An alert will advise you if necessary.
NOTE: The substrate-advance sensor scans the back side of the substrate, which it expects to be of
a single color and shade. It is not guaranteed to work correctly if the back side has been printed on; in
this case, there may be no alert from the printer, but the sensor should be turned off.
Color calibration
Color calibration enables your printer to produce consistent colors with a particular substrate type, even
if printheads, ink cartridges and environmental conditions change. After color calibration, you can expect
to get prints with the same colors from any two different printers situated in different geographical
locations.
The color calibration test chart is printed using the following print mode, depending on the ink density
used with your substrate.
Six passes for 100% ink density
Eight passes for 150% ink density
Fourteen passes for 250% ink density
●
●
●
For this reason, you are strongly recommended to have fine-tuned the appropriate print mode before
starting color calibration. To fine-tune your substrate preset for a specific print mode, see the User's
guide.
To start color calibration from the HP Internal Print Server, select Substrate > Color calibration, then
click the Calibrate button.
8
Chapter 3 Printer calibration
ENWW
The calibration process is fully automatic and can be performed unattended after you have loaded
substrate of the type you wish to calibrate. The process takes about 18 minutes and consists of the
following steps.
1. The Closed-Loop Color Calibration and Ink Restriction Test Chart is printed, which contains scales
of patches of each ink used in your printer.
2. The test chart is scanned and color-measured using the HP Embedded Spectrophotometer. If the
scan cannot be completed successfully, a message is displayed on the front panel; see Color
3. From the measurements made by the spectrophotometer, the printer calculates the necessary
correction tables to apply to your print jobs, for consistent color printing on that substrate type.
Calibration should be done in any of the following circumstances:
Whenever a printhead is replaced
●
●
Whenever a new substrate type is introduced that has not yet been calibrated with the current set
of printheads
Whenever you notice excessive color differences between prints. Such color differences can be
caused by aging and wear of the printheads, changes in substrate characteristics between one roll
and another, changing environmental conditions and so on.
●
Whenever you replace a printhead, an alert will remind you to perform color calibration, unless you have
disabled the alerts. If printhead alignment and/or substrate-advance compensation are also needed,
color calibration should always be the last operation.
You can check the color calibration status of your substrates with the HP Internal Print Server or the
front panel. In the HP Internal Print Server, select Substrate > Color calibration > Show all.
Default status indicates that the substrate has never been calibrated. In this case, the factory
●
default color tables will be applied to print jobs.
Done status indicates that a color calibration has been performed successfully on this substrate.
●
●
Obsolete status indicates that a printhead has been changed since the substrate was last
calibrated, and therefore the substrate should be recalibrated.
ENWW
Color calibration
9
Color calibration is based on the color measurement of printed color patches, using the HP Embedded
Spectrophotometer. Some characterisitics of substrates, such as surface roughness or transparency,
may make reflective color measurement of some substrate types very inaccurate. Color calibration of
these substrates will fail or produce unacceptable printing results.
The suitability of particular substrate types for color calibration can be found in the table of supported
substrate types in the User's guide. Only substrates wider than 36 inches (914 mm) can be calibrated.
It is possible to recover from a bad color calibration by restoring the factory default calibration. In the
HP Internal Print Server, select Substrate > Color calibration > Reset.
You should calibrate a substrate type before creating its color profile; however, you can later recalibrate
without needing to recreate the color profile.
Ink restrictions
Ink restrictions allow you to set the maximum amount of each primary ink (cyan, magenta, yellow, black,
light cyan, light magenta) that can be laid down onto a given substrate.
To adjust ink restriction percentages from the HP Internal Print Server, select Substrate > Edit >
Color.
Ink restriction percentages can be set from 50% to 100% for all inks by filling in the appropriate boxes.
In general, a figure of about 80% is recommended.
High percentage settings (approaching 100%) use more ink and may therefore increase color gamut,
at the cost of leaving less margin for the operation of the color calibration system, which may reduce
color consistency.
Lower percentages use less ink, provide a smaller color gamut and a higher range of compensation for
best color consistency.
NOTE: Ill-defined ink restrictions may lead to unpredictable results. You can restore the default ink
restriction settings by selecting Substrate > Edit > Color > Reset.
The Closed-Loop Color Calibration and Ink Restriction Test Chart contains printed ink ramps in 2%
steps, which can be useful as a visual guide for selecting the ink restriction percentages.
To print the Closed-Loop Color Calibration and Ink Restriction Test Chart, select Substrate > Edit >
Color > Print plot.
Color profiles
Color calibration provides consistent colors, but consistent colors are not necessarily accurate. For
instance, if your printer prints all colors as black, its colors may be consistent but they are not accurate.
In order to print accurate colors, it is necessary to convert the color values in your files to the color values
that will produce the correct colors from your printer, your inks and your substrate. An ICC color profile
is a description of a printer, ink and substrate combination that contains all the information needed for
these color conversions.
These color conversions are performed by your Raster Image Processor (RIP), not by the printer. For
further information on the use of ICC profiles, see the documentation for your application software and
for your RIP.

4 Hardware maintenance
Maintain the ink cartridges
During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to
maintain the best print quality, replace a cartridge when it reaches its expiration date. An alert notifies
you when any cartridge reaches its expiration date.
Maintain the printheads
During the normal lifetime of a printhead, no regular maintenance is required. However, in order to
maintain the best print quality, replace a printhead when it reaches its expiration date. An alert notifies
you when any printhead reaches its expiration date.
Printheads may need to be cleaned and aligned from time to time: see Clean the printheads
TIP: If you remove an unexpired printhead from the printer, planning to reuse it later, the best way to
protect it is by replacing the protective caps that you removed before inserting it into the printer.
Maintain the substrates
Keep substrates in their sealed wrapping material while they are in storage, and store rolls vertically to
avoid the migration of plasticizers in some materials.
Move substrates from the storage area to the print production area at least 24 hours before use, so that
they can adapt to its temperature and humidity.

parts.
7. Look for condensation under the carriage, and remove it with a clean lint-free cloth if necessary.
8. Press the OK button on the front panel. The printer lowers the carriage beam to its normal position.
WARNING! Do not insert your hands or anything else into the printer while the carriage is
descending.
Clean the main roller
The main roller should be cleaned whenever it is visibly dirty, or when you notice that substrate advance
is no longer smooth and regular.
Clean the main roller with a clean cloth dampened with water, and make sure that the roller is dry before
printing. Do not use petroleum-based cleaning liquids.
Clean the substrate edge holders
If you sometimes print with very small side margins, ink may accumulate on the substrate edge holders,
which can cause smears on your prints and blocked nozzles in the printheads.
Check the substrate edge holders monthly for dried ink. If necessary, clean them with a lint-free cloth
dampened with isopropyl alcohol.
TIP: It is not normally necessary to remove the edge holders from the printer, and doing so may
damage them. When not required, they can simply be pushed to the side, away from the substrate.
ENWW
Clean the main roller 17
Clean the pinch wheels
If the pinch wheels are dirty, they can be cleaned by advancing the substrate (less than a meter).
Cleaning the wheels manually could damage them, and is not recommended.
Clean the platen
The platen should be cleaned whenever it is visibly dirty, or when you notice marks on the back of the
substrate.
Before cleaning the platen, locate the substrate-advance sensor and be careful to avoid scratching it
Clean the platen with a clean cloth dampened with water, and make sure that the platen is dry before
printing.
Clean the printheads
Periodic printhead cleaning is performed automatically, as long as the printer is turned on. However,
you should clean the printheads if you are experiencing poor image quality and cannot resolve the issue
by other methods. This ensures that there is fresh ink in the nozzles and helps to prevents clogged
nozzles.
If you have printed the printhead status plot, you know which colors are failing. Clean the printheads
that are not performing adequately. If you are not sure which printheads to clean, clean all of the
printheads.
To clean the printheads, go to the HP Internal Print Server and select Printer > Printhead cleaning.
HP recommends the Check and Clean option.
If you decide on a hard clean, you can select which printheads to clean.
Clean the substrate-advance sensor
No alert is displayed to remind you to clean the substrate-advance sensor. You should clean it
periodically (every one to three months, depending on the printer usage and substrate type—see note
below), whenever you clean the platen, and whenever you have printed by accident directly onto the
NOTE: Porous substrates or liners can allow small amounts of ink to pass through to the platen and
sensor window, to the extent that a clean sensor can become dirty before finishing a single roll. For this
reason, it is best to disable the sensor when loading a porous substrate, and to clean the platen and
sensor before loading another substrate.
18 Chapter 4 Hardware maintenance
ENWW
The sensor is located between the second and third group of three pinches, in the middle of the platen.
TIP: You may need a ladder to reach the sensor.
TIP: Cleaning is easily done by reaching over the carriage beam in its low position. If you try to do it
by putting your arms below the beam in its high position, you will find it more difficult to access the sensor
and to check that it is clean.
1. Unload the substrate.
2. Wipe the sensor with one of the cotton swabs provided in the Cleaning Kit, slightly dampened with
isopropyl alcohol, to remove dried ink. If the sensor window is heavily coated with dried ink, you
may need to apply some pressure while wiping, helping the cotton to absorb the ink. Continue
cleaning with fresh swabs until the cotton stays clean and the sensor window looks clean.
When reflecting ambient light, a clean sensor shows a blue-colored reflection that should extend
uniformly across its whole surface. You can see this reflection by moving closer and slightly
changing your angle of view.
3. Wait 3 or 4 minutes before reloading the substrate, so that the alcohol can evaporate completely.
Clean the temperature sensors
An alert is displayed when the temperature sensors need to be cleaned, which may be about every two
months, depending on your use of the printer. When you see the alert, follow this procedure to clean
the sensors.

6 Troubleshoot substrate issues
The substrate cannot be loaded successfully
A substrate cannot be loaded unless all printer subsystems (e.g. the ink system) are ready.
●
If the printer is unaware of the carriage beam position (after a printer recovery or shutdown), go to
●
the front panel and select the Substrate Management icon
, then Carriage beam position
> Carriage system recovery.
Check that the spindle is correctly inflated.
●
●
Try using the front panel to advance the substrate at least 10 ft (3 m), then move it back and try to
load it again. If it will not load, perhaps the substrate is not attached to the input core: try a different
roll.
The substrate has jammed
If the printer reports a substrate jam, follow these steps.
1. If the carriage is still moving or trying to move, press an emergency stop button as quickly as
possible to minimize damage to the printheads.
If the printer shuts itself down automatically before you reach an emergency stop button, turn off
circuit breaker ACB-1.
2. Wait about ten minutes for the printer to cool down.
ENWW
The substrate cannot be loaded successfully 31
3. If feasible, manually move the carriage slowly and carefully to the side, away from the substrate.
If this is not feasible because of the severity of the jam, try raising the carriage beam to its maximum
height.
4. Remove all substrate and pieces of substrate from the printing zone and from any other parts of
the printer into which they may have fallen. Check the curing zone in particular. If you are unable
to remove them all, please call your service representative (see HP Customer Care Centers
5. Before restarting the printer and reloading the substrate, check that all circuit breakers are on and
all emergency stop buttons released.
The substrate is not attached to the input core
If the roll is not firmly attached to the input core, you may see banding on your prints, or the printer may
report the end of the roll. To correct the problem, proceed as follows.
1. Unload the roll from the input spindle and load it onto the output spindle. Take care to avoid
telescoping.
2. Raise the pinches and, in the front panel's Substrate Management menu, raise the carriage beam
to its maximum height.
3. Unload substrate from the roll and pass it backwards through the printer towards the input spindle.
Attach it to the empty core on the input spindle, securing it with adhesive tape. Wrap a couple of
turns of substrate around the input core. Take care to align the substrate with the output roll.
4. Lower the pinches.
5. At the front panel, exit the Substrate Management menu, replying “Yes” when asked about
checking the substrate.
NOTE: If the substrate check fails, return the roll to the input side and attach it to an empty core
on the output side. Raise the pinches and use the front panel's Substrate Management menu to
move all the substrate onto the output core.
6. Select the correct substrate in the HP Internal Print Server.
7. Press the Form Feed key on the front panel, then the Back key, and wait until all the roll has been
wound onto the input spindle.
8. You may decide to cancel rewinding when the substrate is detached from the output roll. Then
attach it to the output core to print immediately, or rewind it completely onto the input core if you
want to remove the roll.
32 Chapter 6 Troubleshoot substrate issues
ENWW
The substrate sticks to the platen
When the substrate sticks to the platen, the most likely causes are excessive heat and excessive
vacuum. Therefore, try decreasing the drying temperature or the vacuum.
For information on how to adjust printer settings, see the User's guide.
The ink is still wet when the substrate emerges
1. Reduce the ink limits.
2. Increase temperature settings for drying and curing.
For information on how to adjust printer settings, see the User's guide.
There are ink marks on the substrate
This problem can be caused by the carriage touching the substrate and smearing the ink.
1. If the ink marks occur at the sides of the substrate and not in the center, check that the substrate
edge holders are correctly placed.
2. Check that the vacuum and tension levels are correct.
3. If you see large drops of ink, clean the printheads to remove any loose fibers.
For information on how to adjust printer settings, see the User's guide.

7 Troubleshoot print-quality issues
General advice
When you have any print-quality problem:
To achieve the best performance from your printer, use only genuine HP supplies and accessories,
whose reliability and performance have been thoroughly tested to give trouble-free performance
and best-quality prints. For details of recommended substrates, see the User's guide.
●
Check that the substrate type selected in the HP Internal Print Server is the same as the substrate
type loaded into the printer.
●
CAUTION: If you have the wrong substrate type selected, you could experience poor print quality
and incorrect colors, and perhaps even damage to the printheads.
Check that your substrate has been color-calibrated.
●
●
●
Check that you are using the correct ICC profile for your substrate and print mode.
Check that you are using the most appropriate print-quality settings for your purposes (see the
User's guide).
Check that the environmental conditions (temperature, humidity) are in the recommended range
●
(see the User's guide).
Check that the printheads have been aligned.
●
●
●
Check whether there are any outstanding printer alerts.
Avoid touching the substrate while printing is in progress.
Banding
Banding means that your printed image suffers from added horizontal lines as shown (the color of the
lines may vary).
34 Chapter 7 Troubleshoot print-quality issues
ENWW
If there are thin white lines across the width of the substrate:
1. From the HP Internal Print Server, clean and check the printheads, and check for blocked nozzles.
If there are blocked nozzles, increase the number of passes.
●
●
If there is a substrate-advance problem, decrease the substrate-advance setting.
2. If the problem persists, increase the number of passes.
If there are thin dark lines across the width of the substrate:
1. Increase the substrate-advance setting in the HP Internal Print Server.
2. If the lines are visible only in dark or saturated colors, try the following remedies in this order:
a. Increase the number of passes.
b. Lower the ink limit for the selected print mode.
c. Increase the drying temperature.
If you have adjusted the substrate-advance setting but there are still white and dark lines distributed
randomly across the same print:
1. Check the substrate-advance status in the HP Internal Print Server. If there is a warning message:
a. Unload the substrate and clean the substrate-advance sensor.
b. Reload the substrate and check it as usual.
c. If the warning message persists, probably the substrate type is invisible to the substrate-
advance sensor, so you should turn off the sensor (in the Loaded Substrate window in the HP
Internal Print Server) and adjust the substrate advance manually.
2. If the problem persists, increase the number of passes.
3. If the problem persists, recreate the substrate preset.
If there are one or more thick lines across the width of the substrate, where one color seems to be
missing:
2. Open the door on the front right of the printer and pull out the printhead cleaning roll assembly.
3. You should see ink on the upper, horizontal part of the roll and also on the vertical part of the roll.
If you see no ink on the vertical part of the roll, there may be a fault in the primer pump. In this case,
ENWW
Banding 35
If the back side of the substrate varies in color or shade (for instance, if something has been printed on
it), you may see banding in parts of your print because the substrate-advance sensor has become
confused. In this case, turn off the sensor (in the Loaded Substrate window in the HP Internal Print
Server) and adjust the substrate advance manually.
If you see banding while printing on self-adhesive substrate with four or five passes, press the
Change button in the Job Properties window, and try changing the halftoning method to G.N.
For information on how to adjust printer settings, see the User's guide.
Colors are misaligned
This problem can have various slightly different visible symptoms.
Colors are misaligned vertically
If magenta prints higher on the substrate than the other colors, increase the substrate-advance
setting in the HP Internal Print Server.
●
●
●
If magenta prints lower on the substrate than the other colors, decrease the substrate-advance
setting in the HP Internal Print Server.
If the misalignment appears to be random, try the solutions recommended for banding (see
36 Chapter 7 Troubleshoot print-quality issues
ENWW
Colors are misaligned horizontally
1. Ensure that the substrate is not skewed. If there is any skew, reload the substrate to correct it.
2. Check the carriage beam position. If it is high and the substrate type doesn't require a high position,
lower it.
3. If the problem persists, realign the printheads.
4. If the problem persists despite automatic printhead alignment, try manual printhead alignment.
5. If the misalignment appears at the sides of the substrate but not in the center, you have a problem
of substrate expansion.
If you are using a plastic substrate, recreate the substrate preset, decreasing the curing and
drying temperatures as much as possible.
●
●
●
If you are using a porous, paper-based substrate, recreate the substrate preset, increasing
the drying temperature as much as possible.
Some substrate types (especially paper-based substrates) may expand because of the
ambient temperature and humidity. Try using a higher-quality substrate that is less sensitive
to temperature and humidity.
If you see the problem in printed black text, check in your application or in the RIP that the
text color is pure black and does not contain other colors.
●
The print is grainy
1. Check that you are printing on the correct side of the substrate.
2. Make a diagnostic print and adjust the substrate-advance setting.
3. If the problem persists, align the printheads.
4. If the graininess is more visible in dark or saturated colors (coalescence):
ENWW
The print is grainy 37
a. Increase the number of passes.
b. Increase the drying temperature.
c. Decrease the ink limit.
For information on how to adjust printer settings, see the User's guide.
The print is smudged
This indicates that the ink is not dry. The characteristics of the substrate may have changed. Recreate
the substrate preset.
The substrate is not flat
If the substrate does not lie flat when it comes out of the printer, but has shallow waves in it, you are
likely to see defects in the printed image, such as vertical stripes. This can happen when you use thin
substrate that becomes saturated with ink.
1. Check that the substrate type you have loaded corresponds to the substrate type selected in the
front panel and in your software.
2. Try changing to a thicker substrate type.
Edges of objects are rough or blurred
1. Check that the carriage beam position is not high. If it is high, the printheads have to be aligned
manually.
2. Align the printheads.
3. Recreate the substrate preset.
For information on how to adjust printer settings, see the User's guide.
Colors look washed out
1. If you are using fewer than four passes, increase the number of passes.
2. Increase the ink density.
3. Check that you are using the correct ICC profile for your substrate and print mode.
For information on how to adjust printer settings, see the User's guide.

8 Troubleshoot ink cartridge and
printhead issues
Cannot insert an ink cartridge
1. Use the correct procedure to change ink cartridges, through the front panel. See the User's
guide.
2. Check that there is no obstruction in the ink cartridge connector.
3. Check that the ink cartridge is of the correct color. A connector will refuse to connect to a cartridge
of the wrong color.
4. Check that the ink cartridge is correctly oriented (compare with the others).
Cannot insert a printhead
1. Use the correct procedure to change printheads, through the front panel. See the User's guide.
2. Check that there is no obstruction in the printhead slot.
3. Check that the printhead is correctly oriented (compare with the others).
4. Check that you have closed and latched the printhead cover.

A printhead has overheated
A printhead may overheat for several reasons.
The room temperature may be too high.
●
●
The printhead may be suffering from blocked nozzles. You may be able to cure this problem by
The printhead may be suffering from an internal failure, in which case it must be replaced.
●
A printhead has damaged the substrate
When a printhead touches and damages the substrate, the most likely cause is excessive heat.
Therefore, try decreasing the drying temperature.
For information on how to adjust printer settings, see the User's guide.
Incorrect printhead cleaning roll errors
You should not touch the printhead cleaner roll except when you need to replace it. Any interference
with the roll may prevent the printer from keeping track of roll usage, in which case you may see spurious
error messages, and a printing job may be cancelled unnecessarily.

Color calibration fails
Automatic color calibration may fail occasionally. You may see the front panel error message Color
calibration cancelled because of scanning errors, which can be caused by various different
problems.
Reflective color measurements of the printed target cannot be performed reliably on the current
substrate. Reflective color measurement can be unreliable or impossible on substrates that are
non-white, transparent or translucent, very glossy, or have a very rough or punched surface. For
these substrates, automated color calibration using the HP Embedded Spectrophotometer may
not be possible; see the table of supported substrate types in the User's guide. Adjustment of ink
restrictions is still possible using the HP Internal Print Server.
●
Some of the color measurements of the Closed-Loop Color Calibration and Ink Restriction Test
Chart are defective, or the scanning of the fiducial marks (the big black |\\| marks) has failed. These
problems can be caused by:
●
Unwanted stains or printhead crash marks on the substrate, that can be easily seen by visual
inspection of the printed chart. Make sure the substrate has no stains before running color
calibration. Printhead crash marks may occur when the substrate is wrinkled. Try to solve the
problem by adjusting substrate parameters such as tension or drying and curing temperatures.

Service information
The printer can produce on request a list of many aspects of its current status, some of which may be
useful to a service engineer trying to fix a problem. There are two different ways to request this list:
In the HP Internal Print Server, select Information > Service information.
●
●
From any computer with Internet access, enter the URL of your printer into a Web browser, followed
by /hp/device/webAccess/allServicePlot.htm. For instance, if the URL of your printer
allServicePlot.htm.
You can request the whole list, which takes a significant time to generate; or you can request specific
parts of it. If in doubt, you are recommended to request the whole list (select All pages).
If you need to send the list by e-mail, you can save the page as a file from your Web browser, and later
send the file. Alternatively, from Internet Explorer you can send the page directly: select File > Send
> Page by E-mail.
