If the printer is aware of damage to the file system, for instance after a severe software problem, it may
start a file system check automatically. This can take about half an hour.
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 in the front panel and in the Embedded Web Server. In some cases, the printer
may also make an audible beep to draw your attention to the alert. If you do not want to hear the
beeps, you can disable them from the front panel.
●
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.
●

Hardware maintenance
For the tasks in this chapter, you may need the User Maintenance Kit that was provided with your
printer.
Ink system tips
For best results, always follow these guidelines:
●
Follow the instructions on the front panel during installation.
●
Allow the printer and the printhead cleaning cartridge to clean the printheads automatically.
●
Avoid unnecessary removal of the ink cartridges and printheads.
●
The ink cartridges should never be removed while the printer is printing. They should be removed
only when the printer is ready for you to replace them. The front panel guides you through the
replacement procedure.
●
Make sure that you comply with all applicable laws and regulations when disposing of ink system
consumables.
Maintain hardware
NOTE: Shake the ink cartridges and printheads vigorously before installing them.
Align the printheads
The printer performs printhead alignment whenever printheads are replaced. If no substrate is loaded
when a printhead is replaced, the printer will perform the alignment the next time you load substrate.
You may also be recommended to align the printheads to solve a print-quality problem.
Automatic alignment
First make sure that you have a roll of opaque, white substrate loaded in the printer. Colored
substrates, glossy canvas, and transparent materials such as translucent bond, clear film, tracing
substrate, and vellum are not suitable for automatic printhead alignment; for these substrates, you
should align the printheads manually (see Manual alignment on page 10).
To request printhead alignment from the front panel (if the alignment is not performed automatically),
icon, then select Image quality maintenance > Align printheads > Auto PH
select the
alignment.
To request printhead alignment from the Embedded Web Server, select the Setup tab, then select
Printhead alignment > Automatic printhead alignment > Print.
ENWW
Ink system tips
9
The process takes about 10 minutes and starts immediately, unless an image is currently being printed.
If a print job is in process, the alignment will be done as soon as the current print job is finished.
Manual alignment
To request a manual printhead alignment from the front panel, select the
icon, then select Image
quality maintenance > Align printheads > Manual PH alignment > Print alignment
pattern.
To request manual printhead alignment from the Embedded Web Server, select the Setup tab, then
select Printhead alignment > Manual printhead alignment > Print.
The printer prints 17 rows labelled from A to Q. Inspect the print and write down the number of the
straightest line in each row (for example, A:9).
When you have done this, enter the correction values into the front panel or the Embedded Web
Server.

To enter the correction values in the Embedded Web Server, select the Setup tab, then select
Printhead alignment > Manual printhead alignment, and enter each value into the window
labelled with the same letter as the corresponding pattern.
Check substrate porosity
To check the porosity of your substrate, proceed as follows.
10
1.
If the printer has any substrate loaded, unload it.
2.
Cut a piece of self-adhesive vinyl white gloss 15 × 50 mm (0.6 × 2 in) in size.
Chapter 4 Hardware maintenance
ENWW
Stick it to the platen as shown.
4.
Load the substrate that you want to check.
5.
Open your RIP software.
6.
Download the test file from inside the printer: http://printerIP/hp/device/webAccess/
images/Ink_trespassing_check.pdf, where printerIP is the IP address of your printer.
7.
Print the test file using the number of passes and media profile that you intend to use in future with
this substrate (or a similar profile in terms of ink limit).
8.
Unload the substrate.
9.
Remove the strip of self-adhesive vinyl from the platen.
Maintain hardware
3.
10. Compare the optical density (darkness) of the strip with the gray rectangle below.
ENWW
●
If the strip is completely white (has no ink on it), the tested substrate is non-porous and can be
used for printing as described in the User's guide.
●
If the strip is lighter than the gray rectangle above, the tested substrate can be used for
printing, but the platen should be cleaned immediately after each printing session (see Clean
the platen on page 15).
●
If the strip is darker than the gray rectangle above, the tested substrate is too porous, and is
not supported for use with your printer.
Check substrate porosity
11
Clean the electrical connections on a printhead
It is possible that the printer will not recognize a printhead after it has been installed. This can happen
when ink builds up on the electrical connections between the printhead and the printhead carriage.
Under these circumstances, HP recommends that you clean the electrical connections on the printhead.
However, routine cleaning of the connections when no problems are apparent is not recommended.
A carriage interconnect wiper is included with your printer in the User Maintenance Kit.
Use this to clean the electrical interconnects on both the printhead carriage and the printhead if the
Reseat or Replace message persists next to the printhead on the front-panel display.
1.
Remove a new pre-moistened replacement sponge from its pouch.
Maintain hardware
A supply of sponges is included in the box with the wiper. If all sponges have been used, more
can be obtained by calling your service representative.
2.
12
Open the carriage interconnect wiper.
Chapter 4 Hardware maintenance
ENWW
3.
Load the sponge by positioning the sponge on the face of the carriage interconnect wiper with the
shorter tab in the locating slot.
4.
Close the carriage interconnect wiper, trapping the sponge in place.
5.
Open the printhead carriage latch and extract the printhead that is causing the problem, as
indicated on the front panel. See Replace a printhead on page 30.
6.
Insert the carriage interconnect wiper into the printhead slot at the back. Wipe the electrical
contacts by inserting the tool between the electrical connections at the back of the slot and the
steel spring, with the sponge facing away from you and towards the electrical contacts. Try to
avoid picking up any ink deposit that may have accumulated on the bottom surface of the slot.
7.
ENWW
Maintain hardware
CAUTION: If the carriage remains in the central part of the printer for more than 7 minutes, it
attempts to return to its home position to the right.
Rub the sponge against the contacts with a light force along the entire depth of the flex connector,
inserting the wiper as far as allowed by the mechanical stop on the tool.
Clean the electrical connections on a printhead
13
8.
Take special care to clean all contacts thoroughly, including the ones at the lowest point of the
connector.
9.
Using the same sponge, clean the lower strip of electrical contacts on the printhead (unless the
printhead is new). Avoid touching the upper set of electrical contacts.
CAUTION: Do not touch the surface of the printhead that contains the nozzles, because the
nozzles are easily damaged.
10. After waiting a few moments to allow both connectors to dry, replace the printhead into the
printhead carriage. See Replace a printhead on page 30.
11. After completing the cleaning process, open the carriage interconnect wiper by pulling on the
sponge tab.
Maintain hardware
12. Remove the soiled sponge from the carriage interconnect wiper.
14
Chapter 4 Hardware maintenance
ENWW
13. Dispose of the soiled sponge in a safe place to prevent the transfer of ink onto hands and clothing.
If the front panel continues to show the Reseat or Replace message, replace the printhead or call
your service representative.
Clean the exterior of the printer
Use a damp sponge or a soft cloth and a mild household cleaner such as non-abrasive liquid soap to
clean the outside of the printer and all other parts of the printer that you regularly touch as part of
normal operation (for example, ink cartridge drawer handles).
There may be some dampness from condensation under the fans of the curing module, which should be
wiped with a dry cloth.
WARNING! To avoid an electric shock, make sure that the printer is turned OFF and unplugged
before you clean it. Do not let water get inside the printer.
CAUTION: Do not use abrasive cleaners on the printer.
Clean the platen
Maintain hardware
You should clean your printer's platen every few months, or when necessary.
NOTE: If you print on wide substrate after having printed on narrower substrate, you may find that
the left side of the platen has become dirty. If this contaminated section of the platen is not cleaned, it
could leave marks on the back of the substrate.
CAUTION: Be careful not to damage the substrate-advance sensor when cleaning the platen. The
sensor is the very small rectangular window (less than 1 cm²) found close to the third pinchwheel from
the right. See Clean the substrate-advance sensor window on page 18.
Follow these instructions to clean the platen.
ENWW
1.
Unload all substrate from the printer. See the User's guide.
2.
Turn off the printer and wait until it has cooled down, then unlock and open the printer window.

Clean after porous substrates
If you print on a porous substrate (through which ink can pass), you should clean the platen
immediately after each printing session. Do not, for instance, leave the printer overnight or load a new
roll without cleaning the platen first.
When printing on a textile or thin substrate, you may find condensation in the input area of the printer.
You are recommended to wipe it away with a dry cloth, at least before loading a new roll.
Clean (recover) the printheads
To clean the printheads (which often enables them to recover from problems), go to the printer's front

Cleaning all printheads takes about 5 minutes. Cleaning any two printheads takes about 3 minutes.
NOTE: Cleaning all printheads uses more ink than cleaning a single pair.
Clean the substrate-advance sensor window
The substrate-advance sensor is the very small rectangular window (less than 1 square centimeter in
size) close to the third pinchwheel from the right.
HP recommends that you clean the substrate-advance sensor window whenever you clean the print

Wipe the sensor with one of the cotton swabs provided in the User Maintenance Kit, slightly
dampened with 95% ethanol, to remove dried ink.
NOTE: 95% ethanol is not provided in the User Maintenance Kit.
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.

10. For correct environmental storage conditions, see the specifications in the User's guide.
NOTE: If the printer or ink cartridges are moved from a cold location to a warm and humid location,
water from the atmosphere can condensate on the printer parts and cartridges and can result in ink
leaks and printer errors. In this case, HP recommends that you wait at least 3 hours before turning on
the printer or installing the ink cartridges, to allow the condensate to evaporate.
Replace an ink cartridge
Ink cartridges should be replaced for the following two reasons:
●
The ink cartridge is very low and you want to replace it with a full cartridge for unattended
printing. You can use the remaining ink in the first cartridge at a more convenient time.
●
The ink cartridge is empty or faulty, and you must replace it to continue printing.
CAUTION: The procedure to remove an ink cartridge must be initiated from the front panel. Do not
remove an ink cartridge until the front panel prompts you. If you remove an ink cartridge incorrectly,
the printer may subsequently reject that cartridge.
Maintain hardware
CAUTION: Remove an ink cartridge only if you are ready to insert another one.
CAUTION: Avoid touching pins, leads and circuitry when handling ink cartridges because these
elements are sensitive to electrostatic discharge, which can reduce the life expectancy of the device.
WARNING! Make sure that the printer wheels are locked (the brake lever is pressed down) to
prevent the printer from moving.

Refilled and non-HP ink cartridges
HP recommends that you replace an empty cartridge with a new HP cartridge.
The use of refilled or non-HP ink cartridges has several disadvantages.
●
If printer failure or damage is attributable to the use of a non-HP or refilled ink cartridge, HP will
charge its standard time and materials charges to service the printer for the particular failure or
damage.
●
If failure or damage to printheads, ink cartridges, or other ink supplies is attributable to the use of
non-HP, expired or refilled ink cartridge, HP is not responsible for the cost of replacement.
●
Print quality may be impaired.
●
The printer will be unable to estimate the ink level in the cartridge, and will report it as empty.
If you decide to use refilled or non-HP ink cartridges, you will need to follow these instructions to make
the printer use a cartridge that it believes to be empty.
Maintain hardware
CAUTION: Running completely out of ink can damage the printheads. Damage attributable to
printing with empty ink cartridges is not covered under warranty. Forcing the printer to accept empty
cartridges will empty the ink delivery system as well. Once emptied, ink must be used to refill the system
and reprime the printhead when a new ink cartridge is installed.

Service maintenance
During the life of your printer, components that are used constantly can wear out.
To avoid having these components degrade to the point that the printer breaks down, the printer keeps
track of the number of cycles that the printer carriage makes across the axis of the printer, and also
monitors the total quantity of ink used.
The printer uses these numbers to track the need for service maintenance, and displays one of the
following messages on the front panel:
●
Service Maintenance Kit 1
●
Service Maintenance Kit 2
●
Service Maintenance Kit 3
Maintain hardware
These messages mean that some components are nearing the end of their lives. You can continue
printing for quite some time, depending on your use of the printer. However, HP strongly recommends
that you call your service representative and arrange for a service maintenance visit. The service
engineer can then replace the worn parts on-site, which will prolong the life of the printer.
The benefits of arranging a service engineer's visit when these messages appear on the front panel are
two-fold:
40
●
The printer components can be replaced at a time that is convenient for you, and so will not
disturb your daily workflow.
●
During a service maintenance visit, the service engineer replaces several parts at once. This
eliminates the need for repeat visits.

Substrate settings
Download media presets
Each supported substrate has its own characteristics. The printer changes the way it prints on each
different substrate. The RIP requires a description of the requirements of each substrate. This description
is called the “media preset”.
The media preset contains the ICC color profile, which describes the color characteristics of the
substrate. It also contains information about other characteristics (RIP and printer settings) and
requirements of the substrate that are not directly related to color. Media presets for your printer are
installed in the RIP.
The RIP contains media presets for only the most commonly used substrates. If you buy a substrate for
which your RIP has no preset, you can obtain a preset for a new substrate in the following ways:
●
Try to download the media preset from the substrate manufacturer's Web site.
●
If it is not there, try to download it from the RIP company's Web site.
●
If it is not there, check availability using the HP Media Finder search application located at
http://www.hp.com/go/latexmediafinder/
●
If you cannot find it anywhere, create a new media preset in the RIP. See Add a new substrate
on page 41.

Setting
Description
If too low
If too high
Passes
The number of passes specifies
how many times the printheads
will print over the same area of
the substrate.
The amount of ink fired per time
unit is larger and ink has less
time to dry on the substrate. This
may create coalescence and
banding. The boundaries
between passes may be more
visible. However, printing speed
is relatively high.
Colors are vivid, print quality is
high. However, printing speed is
relatively low. A lower curing
temperature is needed,
otherwise the substrate may be
deformed.
ENWW
The heat applied in the printing
zone removes water and fixes
the image to the substrate.
Print-quality defects such as
banding, bleeding and
coalescence may occur.
Thermal marks may be seen on
the substrate; they may appear
as vertical bands in some colors.
The substrate may wrinkle on the
platen, causing vertical banding,
ink smears or substrate jams.
Curing temp.
Curing is needed to coalesce the
latex, creating a polymeric film
which acts as a protective layer,
while at the same time removing
the remaining co-solvents from
the print. Curing is vital to
ensure the durability of the
printed images.
The print may emerge not fully
polymerized, so that the ink
smears when rubbed. The print
may appear wet, after printing
or later. You may need to
increase the number of passes to
achieve adequate curing.
The substrate may wrinkle under
the curing module, causing
defects such as blisters or liner
detachment. The substrate
wrinkles may also cause vertical
banding or ink smears at the
beginning of the following plot.
Heating airflow
Airflow helps to remove the
evaporated water from the print
zone and thus allows more
efficient drying.
In general, use the substrate family default value.

Substrate advance
compensation
Your printer was calibrated at
the factory to ensure that it
advances the substrate
accurately when using supported
substrates in normal
environmental conditions.
However, you may find it useful
to adjust the substrate advance
when printing in an unusual but
stable temperature or humidity
level, or if the substrate-advance
sensor is not working.
You may see horizontal banding
or grain.
You may see horizontal banding
or grain.
Input tension
Tension is applied to the
substrate from the input spindle.
It needs to be constant over the
full width of the substrate, thus
substrate load is a critical
operation.
The substrate skews and may
become increasingly wrinkled in
the printing zone. Also, substrate
advance may be irregular,
resulting in horizontal banding.
The substrate may be
permanently deformed or
damaged. Substrate advance
problems may appear in
extreme cases.
Vacuum
The vacuum applied to the
substrate at the printing zone
helps to hold the substrate down
on the print platen, keeping the
distance to the printheads
constant.
The substrate may lift up off the
platen and touch the printheads.
This can smear the printed
image, cause vertical banding,
cause a substrate jam or even
damage the printheads.
For sticky substrates, friction
could be too high and substrate
advance irregular, resulting in
horizontal banding or irregular
grainy patches.
Bidirectional
Specifies whether printheads
print in both directions, when
moving from left to right and
from right to left.
If Bidirectional is selected, the
amount of ink fired per unit of
time is larger, and therefore print
quality defects such as
coalescence and banding may
occur, especially at the sides of
the plot. However, printing
speed is high.
If Bidirectional is unchecked then
the printing is unidirectional and
the speed is relatively low.
The maximum quantity of ink will
be laid on the substrate (the
High ink level option available
only when the number of passes
is 10 or more). The ink quantity
may be reduced by the RIP color
profile.
If not selected, colors may look
washed-out.
If selected, there can be excess
of ink and some problems
related to poor drying and
curing.
High ink level
TIP: You are recommended to
keep Bidirectional selected in all
cases, increasing the number of
passes if necessary to avoid
coalescence and banding.
TIP: Select High ink level for
backlit and some textile
applications, or if you want high
color saturation.

Cutter
The printer's built-in cutter can
cut the substrate automatically
between each print.
Disable the cutter in the following cases:
●
You want to increase the speed of printing.
●
You want to use the take-up reel.
●
You want to cut the substrate manually.
●
The leading edge of the substrate tends to curl and cause
substrate jams.
In some cases, the cutter is automatically disabled.
Auto tracking
(OMAS)
The substrate-advance sensor
(also known as the Optical
Media Advance Sensor, OMAS)
is located under the print platen;
it can track the substrate
advance automatically.
Disable the sensor in the following cases:
●
The substrate allows ink to pass through to the platen. Clean
the sensor after using this substrate.
●
You are instructed to do so by the front panel, because the
sensor is dirty or unable to track this particular substrate.
Load the substrate and print the diagnostic plot
1.
Load the substrate in the normal way, paying particular attention to the following points.
●
The stop at the right-hand end of the spindle has two possible positions on the spindle.
Always use the leftmost position if possible. Use the rightmost position only if the substrate roll
requires the full width of the spindle.
●
Turn off the substrate-advance sensor (OMAS) in the RIP if the substrate is transparent or
dark, or if the printer recommends you to do so.

NOTE: Extra printhead cleaning shortens the life of the printhead cleaning cartridge.
Advanced settings
Here are some more advanced settings, which you are not recommended to change, unless you have
problems that you cannot resolve any other way.
The drying and curing temperatures used by the printer are determined by adding the offset to the base
temperature. The base temperatures shown in the table are the default values for each substrate family,
but may be changed by the printer depending on the printer settings in use. You cannot change the
base temperatures yourself, but you can change the offsets. The base warm-up drying temperature is
determined by the RIP.
Your RIP may have an option to return all settings to their default values.

Temperature profile
Many of the main and advanced substrate settings are related to temperature control, since this is a
critical area for correct printing results with latex inks on a wide variety of substrates. The diagram
below graphically represents the evolution of drying and curing temperatures during the various
printing phases.
NOTE: Target temperatures and time are not to scale. For the specific values used for a given
substrate type (family), consult the main and advanced settings tables above.
NOTE: tp time can be modified through the printer’s front panel.

lower the total ink limits of the media preset. For a quick solution, you could change to a different
media preset that uses less ink: for example, paper-aqueous presets use less ink than self-adhesive
presets.

paper-aqueous presets.
NOTE: Backlit and some textile substrates usually need to be used with the “High Ink Limit” option
enabled in the RIP.
Faster printing
The obvious way to increase speed is to reduce the number of print passes, although this will tend to
reduce print quality. Bear in mind the following considerations.
●
With fewer than 10 passes, you may see an increase in grain.
●
With fewer than 8 passes, the printer is more sensitive to substrate advance problems.
●
With fewer than 8 passes, you may need to reduce the ink quantity to improve print quality.
●
If you want to use the high ink level option, you must use at least 10 passes.
●
As you reduce the number of passes, the best curing temperature may be more difficult to find,
and may be more sensitive to the ambient temperature and humidity.
●
Concatenating prints saves time, because one can be sent while another is being printed.
●
Disable the cutter: select the
icon, then select Substrate handling options > Enable
cutter > Off. With most substrates, this saves some time at the end of the printing process.
●
Increase the cool-down curing temperatures. This also saves some time at the end of the printing
process, but may cause slight substrate deformation, depending on the substrate.
Substrate settings
Here are some other suggestions for increasing the speed of printing.
See also The printer seems slow on page 77.
Color calibration
The purpose of color calibration is to produce consistent colors with the specific printheads, inks and
substrate that you are using, and in your particular environmental conditions. After color calibration,
you can expect to get identical prints from your printer on different occasions.
Color calibration can be launched from your RIP software; see your RIP documentation for details.
ENWW
Faster printing
51
In outline, the process consists of the following steps.
1.
A calibration test chart is printed.
2.
The HP Embedded Spectrophotometer (or, if you prefer, a different spectrophotometer) scans and
measures the test chart.
3.
The RIP uses the measurements to calculate the necessary correction factors for consistent color
printing on that substrate.
Color calibration with the Embedded Spectrophotometer is not recommended for the following substrate
types. It may be possible to calibrate some of these substrates by using an external color measurement
device.
●
Non-opaque substrates such as clear film, backlit substrates, and some textiles.
●
Substrates with an uneven surface, such as perforated vinyl or punched-window substrates.
●
Substrates that suffer deformation from drying and curing, such as paper-based substrates.
●
Very elastic substrates, such as some textiles without liner.
Substrates suitable for color calibration include even-surfaced adhesive vinyls (neither punched nor
perforated), PVC banners and some opaque, stiff textiles.
Some textiles require the take-up reel for successful printing. However, the take-up reel may fail to cope
with the backward movement of the substrate between the printing and scanning phases of color
calibration. To avoid this problem, proceed as follows.
1.
Ensure that the take-up reel is enabled.
2.
Advance the substrate until the loop-shaper reaches its lowest position.
3.
Manually rewind the take-up reel, using the buttons on the take-up reel motor, to collect the
substrate and raise the loop-shaper until it almost touches the take-up reel spindle.
4.
Set the take-up reel's wind direction to neutral.
5.
Launch color calibration from the RIP.
6.
When the color calibration has finished, you can re-enable the take-up reel.
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.
Substrate settings
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. A 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 color profiles, see the documentation for your application software and
for your RIP.
In addition to the color profiles used for printing, you may wish to calibrate and profile your monitor
(display device), so that the colors you see on the screen relate more closely to those that you see on
your prints.

Color reproduction tricks
Latex inks are a new technology, and there are some important guidelines when doing color
separations (such as when creating or modifying a new media preset within your RIP) that will help to
optimize the printer output in terms of color gamut, ink usage and print quality. These are as follows:
●
To achieve the best dark colors in vinyl gloss and other substrates, use as much black and as little
composite (CMY) as possible when creating the ICC profile.
●
Light inks should be avoided as much as possible in high-density colors such as secondaries and
tertiaries (dark red, blue, green, ...).
●
Light inks should be restricted to the lowest-density colors, starting the use of dark inks as early as
possible. Typically, a color of more than 50% density should not contain any light inks.
●
Light inks should be used at no more than 50% of maximum quantity. An excessive amount of light
inks can create gloss artifacts in vinyl gloss substrates.
Please refer to your RIP documentation for details of how to create or modify media presets.
Substrate settings
Presets for HP-branded substrates have been created following the above recommendations in order to
optimize black and dark colors. You can find the HP media preset for your substrate family at

Troubleshoot print-quality issues
General printing advice
Use the following approach when you have any print-quality problem:
●
Make sure that the substrate type that you select on the front panel, and in your RIP software, is the
same as the substrate type that is loaded in the printer. Make sure that the substrate type has been
calibrated.
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.
●
Make that you are using the correct media profile for your substrate, or that you have followed the
correct procedure to generate a new media profile (see Add a new substrate on page 41).
●
Make sure that you are using appropriate print-quality settings in your RIP software.
●
Make sure that you are using the correct ICC profile for your substrate and print-quality settings.
●
Make sure that your environmental conditions (temperature, humidity) are in the recommended
range. See the User's guide.
●
Make sure that your ink cartridges have not passed their expiration dates. See Maintain the ink
cartridges on page 22.
●
Avoid touching the substrate while printing is in progress.
Use the printhead status plot
The printhead status plot consists of patterns that are designed to highlight printhead-reliability
problems. It helps you to check the performance of the printheads that are currently installed in your
printer, and to determine whether any printhead is experiencing clogging or other problems.
Print the printhead status plot
To print the printhead status plot:
54
1.
Use the same substrate type that you were using when you detected a problem.
2.
Check that the selected substrate type is the same as the substrate type that is loaded into the
printer.
3.
On the printer's front panel, select the
Print all test plots.

icon, then select Image quality maintenance >
ENWW
Troubleshoot images
Interpret the printhead status plot
The print consists of small dashes, one for each nozzle on each printhead.
For each individual colored pattern, make sure that most of the dashes are present.
Corrective action
1.
Clean any faulty printheads. See Clean the printheads on page 73. Then reprint the printhead
status plot to see whether the problem has been solved.
2.
If the problem persists, clean the printheads again, and reprint the printhead status plot to see
whether the problem has been solved.
3.
If the problem continues to persist, replace any persistently faulty printheads. See Replace a
printhead on page 30.
What to do if problems persist
If you still experience print-quality problems after applying the advice in this chapter, here are some
additional tips to consider:
●
Try selecting a higher print-quality option in your RIP software.
●
Check that your printer firmware is up to date. See Firmware update on page 8.
●
Check that you have the correct settings in your software program.
●
Call your service representative. See When you need help on page 86.

If you see this kind of problem:
●
Ensure that the vertical correction option is disabled in the RIP and in the front panel. At the front
icon, then select Image quality maintenance > Disable vertical
panel, select the
correct. (if this option is available).
●
The printheads may be misaligned. This is likely if you have not aligned the printheads for a long
time, or if there has been a substrate jam. Align the printheads if necessary (see Align the
printheads on page 9). You can check whether it is necessary by using the printhead status plot
(see Use the printhead status plot on page 54).
●
If you are printing with eight or more passes, the substrate advance may need adjustment. See
Adjust the substrate advance on page 57.
●
Use a higher number of passes: you will probably see less grain with ten or more passes.
●
If graininess is more visible in dark or saturated colors, there may be a problem of ink
coalescence. Try lowering the ink quantity.
If the problem persists, call your service representative. See When you need help on page 86.
Horizontal banding
Try the following remedies if your printed image suffers from added horizontal lines as shown (the color
may vary).
●
●
If bands affect mostly dark or saturated colors, or only area fills near the edges of the substrate,
the cause could be insufficient drying of the ink, or an inaccurate color profile. Try the following
suggestions.
◦
Reduce the ink quantity.
◦
Increase the number of passes.
◦
Modify your media preset as suggested in Color reproduction tricks on page 53.
If bands affect all colors across the width of the printed image, the cause is probably a substrate
advance problem. Use the front panel to adjust the substrate advance on the fly (see Substrate
advance adjustment on the fly on page 58). If you have dark bands, increase the substrate
advance; if you have light bands, decrease it. When you find the right adjustment, store the value
in the RIP for future prints on the same substrate.
Another cause could be a fiber attached to one of the printheads. Turn off the printer and allow it
to cool down, then remove the printheads one at a time and remove any fibers that you see
attached to them.
56
Chapter 6 Troubleshoot print-quality issues
ENWW
If bands affect only some colors, the cause could be a defective printhead.
◦
Print the printhead status plot (see Use the printhead status plot on page 54). If necessary,
clean the printheads (see Clean (recover) the printheads on page 18).
◦
Clean the printheads again.
◦
Align the printheads (see Align the printheads on page 9). If necessary, align them manually.
◦
Print the printhead status plot again. Identify the printhead with the greatest number of
blocked nozzles, and replace it.
◦
If bands appear and disappear intermittently, go to the front panel and select the
icon,
then Image quality maintenance > Enable extra PH cleaning. Remember to disable
this option when you no longer need it, because it shortens the life of the printhead cleaning
kit.
●
If bands affect most of the colors, the printheads could be misaligned. This is likely if you have not
aligned the printheads for a long time, or if there has been a substrate jam. Align the printheads if
necessary (see Align the printheads on page 9). You can check whether it is necessary by using
the printhead status plot (see Use the printhead status plot on page 54).
●
If banding occurs mostly in black areas, create a new color profile using pure black and not a
mixture of other colors. See your RIP documentation.
If the problem persists, call your service representative (see the User's guide).
Adjust the substrate advance
The substrate advance sensor measures the advance of the substrate and compensates for irregularities
at every pass of the printheads. However, to fine-tune the quality of your print, you may need to
calibrate the rate at which the substrate advances. The substrate advance determines the placement of
dots on the substrate. If the substrate is not advanced correctly, light or dark bands appear in the
printed image and the grain in the print may increase.
You can modify the substrate advance with the Substrate Advance parameter in the RIP's substrate
preset.

the lightest of the columns and enter its number into the RIP's Substrate Advance parameter for the

Substrate advance adjustment on the fly
If you are using no more than six passes, you can fine-tune the substrate advance while printing: select
icon, then select Image quality maintenance > Substrate advance calibration >
the
Adjust substrate advance. Select a value of change from –10 mm/m to +10 mm/m (or mils/inch).
To correct light banding, decrease the value. To correct dark banding, increase the value.
If you are using eight passes or more, a wrong advance adjustment will not produce banding but
graininess, which is harder to assess visually. Therefore, in this case you are recommended to use only
the adjustment plot.
When you have chosen a value and pressed OK, the rest of your job will be printed with that value,
but it will be reset to zero at the end of the job. Add the value found to the Substrate Advance value in
the RIP preset to print all future jobs with the new setting.
A simpler and faster way to adjust the substrate advance while the printer is printing is by pressing the
Move Substrate button on the front panel, which then displays the following instructions.
As you modify the setting, the new setting is applied immediately to the current job by the printer.
When you press OK to save the value, it is saved in the printer to be used throughout the current job.
Vertical banding
There are several different kinds of vertical banding that may be seen.
●
Wide vertical bands visible by darkness or graininess, typically seen on vinyl and banner
substrates in medium-density area fills such as grays, violets and greens
◦
Align the printheads. See Align the printheads on page 9.
◦
Try the automatic correction for vertical banding provided by the RIP. Depending on your
icon,
firmware version, this option may also be provided by the front panel: select the
then select Image quality maintenance > Enable vertical correct. (if this option is
available).
NOTE: Remember to disable the vertical banding correction when you no longer need it,
because it may increase grain.
●
58
Thin vertical bands visible by darkness, typically seen in the first 150–200 mm of the print on vinyl
and banner glossy substrates in high-density area fills or in backlit applications
◦
Reduce the ink quantity if possible.
◦
Disable the cutter.
◦
Increase the number of passes.

Irregular or isolated vertical bands
◦
Increase the vacuum level in steps of 10 mmH2O. Do not exceed the following limits: 20
mmH2O for banners, 35 mmH2O for vinyl, and 50 mmH2O for other substrate families.
◦
In backlit applications, increase the number of passes to 20 or more, and change the drying
temperature up and down in steps of 5°C.
◦
If the banding appears only at the beginning of the print, disable the cutter and advance the
substrate manually about 100–150 mm before the first print.
The print is deformed into a curved shape
This may occur as a result of substrate bow deformation. See The substrate has bow deformation
on page 68.
Misaligned colors
If the colors are misaligned in any direction, the printheads may be misaligned. This is likely if you
have not aligned the printheads for a long time, or if there has been a substrate jam. Align the
printheads if necessary (see Align the printheads on page 9). You can check whether it is necessary by
using the printhead status plot (see Use the printhead status plot on page 54).
Color intensity varies
If some printhead nozzles are in use while others in the same printhead are not, water evaporates
slowly from the ink in the unused nozzles, making the color more intense. Thus, in such cases you may
notice variations in color intensity in areas where the color of the image should be constant.

At the front panel, select the
color variation correction. This correction will then remain enabled until you disable it.
●
If you notice the variation in intensity near one side of the print, try rotating the image by 180
degrees before printing. This may solve the problem in some cases, as all the nozzles are
refreshed whenever they enter the service station between passes.
●
Use your RIP to add lateral color bars on the side of the plot that is close to the ink supplies. The
color bars are designed to exercise all the printhead nozzles, to prevent the problem from
occurring.
NOTE: Not all RIPs provide this option.
●
Add lateral color bars to the image, manually, before printing. In this case, you can either use the
standard colors, or decide to include a particular color in which you have noticed the problem.
The recommended width of each color bar is 3 mm.
Lack of sharpness
If text, lines or solid areas are rough or blurred, the printheads may be misaligned. This is likely if you
have not aligned the printheads for a long time, or if there has been a substrate jam. Align the
printheads if necessary (see Align the printheads on page 9). You can check whether it is necessary by
using the printhead status plot (see Use the printhead status plot on page 54).

Ink smears may be seen on the print for the following reasons.
●
The substrate is skewed. Do not ignore the warning message that appears during the loading

◦
Increase the vacuum level in steps of 10 mmH2O. Do not exceed the following limits: 20

●
Increase the vacuum level in steps of 10 mmH2O. Do not exceed the following limits: 20 mmH2O
for banners, 35 mmH2O for vinyl, and 50 mmH2O for other substrate families.

Make sure that the substrate is stored in the same room in which the printer is located.
Subtle stains or uneven appearance
Subtle color differences may be seen on some substrates if they are stored partially covered after
printing. In the period immediately after printing, such substrates should be stored either totally covered
or totally uncovered. It may be advisable to avoid the prolonged contact of two printed faces. This
problem tends to disappear if the substrate is left uncovered for some time.
Alternatively, some individual rolls of substrate may have a defective coating. The solution in this case
is to use another roll.

There are various different circumstances in which these symptoms can be seen.
●
When there is a big transition from light to dark colors across the length or width of the substrate
Increase the minimum drying power.
NOTE: This solution is specific to this problem, and should not be used in other cases, when it
could cause further problems.
●
When the symptoms can be seen only at the start of the first print after the printer has been idle for
some time (especially when the start of the print uses a lot of ink)
Increase the warm-up drying temperature offset and the warm-up curing temperature offset. If
necessary, increase the stable drying and curing temperatures, or slightly reduce the ink limits.
●
When the symptoms can be seen only at the left and right sides of the print
Increase the drying and curing temperatures, decrease the overall ink quantity and/or increase the
number of passes.
●
When the symptoms can be seen only in certain parts of the print that use a lot of ink
Increase the drying and curing temperatures, decrease the overall ink quantity and/or increase the
number of passes.
●
When the symptoms can be seen only in the center of the print
Check that all fans are working correctly.
●
After reducing the number of passes
Increase the drying and curing temperatures and/or decrease the overall ink quantity.
●
When the oily finish appears minutes or hours after printing
Store the print face-up and uncovered; the effect normally disappears after a while.
NOTE: If you decrease the overall ink quantity, you may notice less color saturation.
The dimensions of the print are wrong
As the substrate is heated during the drying and curing processes, some substrates will shrink (and
some may expand) after the image has been printed. This may be inconvenient if the print has to be
framed or if several prints are to be to be tiled one next to the other.
See The substrate has shrunk or expanded on page 68.

Tiling issues
The most common problems when printing tiles are as follows.
●
Color degradation within individual tiles
In many cases, individual tiles are long and contain very large areas of solid colors. This
combination (long areas of saturated solid colors) may lead to a degradation of printhead
performance, which can then cause degradation of the color inside the tile. To solve this problem,
go to the front panel and select the
icon, then Image quality maintenance > Enable
extra PH cleaning. Remember to disable this option when you no longer need it, because it
shortens the life of the printhead cleaning kit.
●
Color variation tile to tile
In some cases contiguous tiles with the same background solid color may show differences in color
between the right side of the first tile and the left side of the second tile. This is a common issue of
inkjet printers (both thermal inkjet and piezo inkjet), where there are slight color variations as the
swath advances. Since the biggest color differences are between the left edge and the right edge,
the effect may sometimes be seen when putting two tiles together. This issue can easily be
overcome by inverting alternate tiles, which has the effect of placing the right side of the first plot
next to the right side of the second plot and the left side of the second plot next to the left side of
the third, so all contiguous areas have been printed in the same point of the swath and, hence,
have the same color. This is a feature that all RIPs have available.
●
Dimensional variations from tile to tile
Some specific banner substrates may not have uniform dimensional stability when printing very
long tiles. The result is that the length of the tile may be different between the left and the right side
(e.g. a 9 meters long tile may be ~1 cm longer on the right side compared to the left side). While
this is not noticeable with individual plots, it affects the alignment between panels in tiling
applications. Substrate types that show this behavior tend to show it constantly along the roll. So,
when present, this issue can easily be overcome by inverting alternative tiles, which has the effect
of placing the right side of the first plot next to the right side of the second plot and the left side of
the second plot next to the left side of the third, so all contiguous areas belong to the same side of
the roll and, hence, have the same length. This is a feature that all RIPs have available.

The substrate cannot be loaded successfully
Here are some suggestions to try if you cannot load the substrate successfully.
●
Reread the loading instructions in the User's guide, and make sure that you are following them.
●
When loading a textile substrate, remember to use the loading accessory, and select Load with
accessory in the front panel.
●
If automatic loading is unsuccessful, try manual loading instead.
●
The substrate might be loaded at an angle (skewed or mislocated). Make sure that the right edge
of the substrate is aligned with the roll on the input spindle.
●
The substrate might be crumpled or warped, or have irregular edges.
●
If the substrate jams in the substrate path to the platen, the leading edge of the substrate might not
be straight or clean. Remove the initial 2 cm (1 in) of substrate from the roll and try again. This
might be necessary even with a new roll of substrate.
●
Make sure that the spindle is correctly inserted.

14. If you find that you have print-quality problems after a jam, try realigning the printheads. See
Align the printheads on page 9.
Avoiding substrate jams
Substrate jams may be caused by loading the substrate with too much skew: do not ignore the warning
message that appears during the loading process in this case.
They may also be caused by not enough vacuum suction in the printing zone. If you decide to increase
the suction, do not exceed the following limits: 20 mmH2O for banners, 35 mmH2O for vinyl, and 50
mmH2O for other substrate families.
If you experience jams only at the beginning of a print, try the following suggestions.
●
Disable the automatic cutter.
●
Go to the front panel and select the
icon, then Substrate handling options > Extra
bottom margin. Set the margin to 100 mm. If that is not enough, try 150 or 200 mm. This
extra margin will apply only to jobs that start printing when the printer is idle and when the cutter

Troubleshoot substrate
The substrate has shrunk or expanded
During the printing process, some substrates may shrink, while others may expand. If this happens, the
dimensions of the print will not be correct.
As a general rule, you can expect the following percentages of shrinkage:
●
Photorealistic: less than 0.4%
●
Paper-solvent, Paper-aqueous: less than 0.5%
●
Self-adhesive: less than 1.2%
●
Banner: less than 3% shrinkage (if you disable the substrate-advance sensor, less than 7%)
The framing problem may be solved by printing a sample and adjusting the size of the image in the
RIP. You may reuse this value for all your future prints with the same substrate, although special care
must be taken when using banners, as the shrinkage may vary up to 1% depending on the amount of
ink used in the print.
You can expect the following variations from one print to another:
●
Photorealistic, Paper-solvent, Paper-aqueous: less than 0.4%
●
Self-adhesive: less than 0.7%
●
Banner: less than 1%
To solve the tiling problem and improve the repeatability of the printed size, you are recommended to
ensure that the substrate-advance sensor is enabled in the RIP's substrate preset, as this will improve the
stability of the prints over time. You are also recommended to tile together areas with similar amounts
of ink. If this is not possible, print the areas with different amounts of ink as different jobs and modify
the length of the job with less ink in the RIP to match its size with the job with high ink content.
Some RIPs may provide a scaling option that allows you to compensate easily for substrate shrinkage or
expansion; see your RIP documentation.
The substrate has bow deformation
The following substrates may suffer from bow deformation during printing, as a result of which the print
will appear curved.
68
●
Self-adhesive vinyl substrates (some specific calendared vinyls only)
●
Cellulose-based poster papers with no backing nor coating, including HP Photorealistic
Chapter 7 Troubleshoot substrate issues
ENWW
This deformation may be particularly noticeable in the following applications.
●
Printing images that will later be cut automatically or manually. When there is bow deformation,
cutters that are aligned on the sides may lose alignment in the center.
●
Poster printing, if the poster is framed or mounted on a straight surface.
Troubleshoot substrate
The example below shows an original image, the substrate suffering from bow deformation, and the
resulting print, also suffering from bow deformation.
You can use the straightness optimization option in the front panel, or in your RIP software, to
compensate for this effect and restore the original shape of your image.
icon, then select Image quality maintenance > Straightness
At the front panel, select the
optimization, and select a correction value from –15 to +15.
The chosen value should represent the vertical distance in millimeters that the centre of the substrate has
moved with respect to the left and right edges. If the deformation moves the center of the substrate in
the direction of substrate advance, the correction value should be negative; if in the reverse direction,
the correction value should be positive. In practice, the required correction value is normally negative.
TIP: You can use the diagnostic image provided in http://IPaddress/hp/device/webAccess/

Precise alignment between printheads is essential for color accuracy, smooth color transitions, and
sharp edges in graphical elements. Your printer has an automatic printhead alignment process which
runs whenever a printhead has been reseated or replaced.
In the case of a substrate jam, if you have used a custom substrate, or if you are experiencing problems

The printer is not printing
Possible reasons why a file you have sent from your computer is not printing when expected, include
the following:
●
There may be a problem with the electrical power. If the printer is not performing and the front
panel does not respond, check that the power switch at the rear is on, the residual current circuit
breakers are up, the power cable is correctly connected, and the electrical socket is providing
power.
●
Unusual electromagnetic phenomena may exist, such as strong electromagnetic fields or severe
electrical disturbances. Such occurrences can cause the printer to behave strangely, or even stop
working. Turn off the printer by using the Power button on the front panel, wait until the
electromagnetic environment has returned to normal, then turn the printer on again. If the problems
persist, call your service representative.
●
One of the following substrate scenarios may exist:
◦
The substrate name that appears on the front panel does not reflect the substrate that is
loaded in the printer.
◦
There is not a sufficient amount of substrate on the loaded roll to print the entire job.
Under these conditions, one print job might be printed, while another print job is held in the print
queue. To resolve this issue, unload the roll from the printer and load a new roll, using the front
panel to guide you through the process.

The software program slows down or stalls while
generating the print job
Large quantities of data might be necessary to generate a high-quality large-format print job. This can
cause your software program to slow down significantly or stall. Lowering the print resolution may help
to avoid this scenario, however, lowering the print resolution reduces image quality.
The printer seems slow
Here are some possible explanations.
ENWW
●
If you request the highest possible print quality in the RIP, printing will be relatively slow compared
with draft-quality printing.
●
Ensure that the substrate loaded in the printer belongs to the substrate family that appears on the
front panel.
●
Are the printheads in good condition? Printing time tends to increase when a printhead needs
cleaning. Check the printhead status on the front panel or through the Embedded Web Server.
Clean or replace printheads if necessary.
The printer is not printing
77
●
Does your image contain high-density black fills? That may increase printing time.
●
If your printer is connected to a network, check the following points.
◦
Ensure that all components used in the network (network interface cards, routers, switches
and cables) are capable of high-speed operation. All network switches should be Gigabit
switches or at least 100 Mbits/sec (100 baseT); all network cables should be CAT-5e or
better.
◦
Ensure that all network cables are well connected and in good physical condition. Damaged
cables and poor connections at the Ethernet sockets can seriously degrade performance.
◦
Is there a lot of traffic from other devices on the network?
◦
Ensure that no other device on the network is trying to use the same IP address as the printer.
◦
Ensure that the Ethernet link speed is Gigabit (or 100 baseT full duplex if Gigabit is not
possible in your network). This is normally best achieved by setting the link speed to
Automatic in the Embedded Web Server. Ensure that the Ethernet switch or router to which
the printer is connected is also configured for automatic link speed (this is normally the
default case).
◦
Having checked the network connection to the printer, make similar checks (on cables, link
speed settings and duplicated IP addresses) on the connection between the computer and the
Ethernet switch or router.
◦
Remember that firewalls and other software running on the computer may reduce the network
speed significantly.

The front-panel display does not show the Receiving message when you have sent an image to
the printer.
●
Your computer shows an error message when you try to print, such as error 61:09 or 63:05. See
Front-panel error messages on page 80.
●
Your computer or printer stalls when transferring data.
To solve a communication problem:
78
●
Make sure that you have selected the correct printer in your RIP.
●
Remember that large images usually require more time to receive, process, and print.
Chapter 9 Troubleshoot other issues
ENWW
●
If the printer is connected to your computer through any other intermediate devices, such as switch
boxes, buffer boxes, cable adapters, or cable converters, remove the intermediate device and try
connecting the printer directly to your computer.
●
Try another interface cable.
●
Try changing the I/O timeout, which specifies the time that an idle connection is allowed to
remain open when the printer is waiting for a remote computer. The default value is 30 seconds. If
set to zero, the timeout is disabled and the connection is allowed to remain open indefinitely. To
change the I/O timeout, go to the front panel and select the
icon, then Connectivity >
Advanced > Select I/O timeout.

Error code
Recommendation
32:01.1
This error occurs when there is a small amount of substrate printed, less than 79 in (200 cm)
long. Check that there is no obstacle between the take-up reel optical sensors; that the
substrate is attached to the take-up reel spindle; and that the take-up reel switch is in the
correct position. If necessary, use the take-up reel arrow keys to wind the substrate; then press
OK to resume printing.
32:01.2
This error occurs when there is a small amount of substrate printed, less than 70 in (178 cm)
long. The take-up reel sensor detects that the loop shaper is (incorrectly) at the bottom of its
path, even though the spindle motor has been rotating for more than 3 seconds. The most
probable cause of this error is that you have forgotten to set the switch direction or tape the
substrate to the spindle core, when the substrate reaches the floor and blocks the take-up reel's
infrared sensors. Check that there is no obstacle between the take-up reel optical sensors; that
the substrate is attached to the take-up reel spindle; and that the take-up reel switch is in the
correct position. If necessary, use the take-up reel arrow keys to wind the substrate; then press
OK to resume printing.
32:02
This error occurs during printer initialization, to warn you that the take-up reel has been
disconnected while the printer was turned off. It also occurs if you try to enable the take-up
reel, but it is not connected to the printer. Connect the take-up reel to the printer and press OK
to continue.
41:03
Turn off the printer using the front panel and the power switch at the rear. Disconnect the
power cords. Open the window and check for any visible obstacles restricting the movement
of the drive roller. If there is a wrinkled mass of substrate in the substrate path, lift the substrate
adjustment lever and clear the obstruction. Reconnect the power cords and turn the printer on
again. If the problem persists, call your service representative. See When you need help
on page 86.
42:03
