Treat any media, paper, used cleaning and maintenance
supplies, and wipes soaked with ink as combustible
materials. Handle and dispose of properly.
Do not clean the printer with benzene or paint thinner. This
may damage the paint.
Wipe the printer clean with a soft cloth. A cloth moistened
with a neutral detergent may be used. Do not allow liquid to
enter the printer. This may create risk of fire and electrical
shock and cause a malfunction.
Never touch the printhead nozzles. They can be easily
damaged or clogged.
Do not touch heater surfaces in the paper path. This may
cause burns. Take care when touching printer components
near the heaters.
HP Ink Cartridges must be installed before the “Install By”

Troubleshooting
Improving Image Quality when Frequently Printing
Long Prints
Customers who frequently print long prints (more than 10m/33ft) need to
configure some specific printer settings to keep the printheads in good
condition and avoid image-quality issues.
Normal Printer Operation
Low-solvent printheads require frequent maintenance and servicing to keep
the nozzles from becoming clogged. Therefore, in addition to the customer’s
required daily maintenance tasks, the printer performs automatic, periodic
servicing between prints.
During the automatic servicing, the printer performs the following services:
Primes the printheads to unblock any temporarily blocked nozzles.
Wipes the nozzle plate to remove any residual solvent ink that may have
accumulated around the nozzles to reduce the chances of nozzle
blockage with additional usage.
Opens the capping units to remove any ink accumulation inside the caps.
These processes are necessary to ensure the correct functioning of the
printhead, which affects the image quality of the printed image.
When printing an average job, automatic servicing is done between prints.
After a predetermined length of media has been printed, the printer
performs the automatic servicing procedure. The amount of media that is
printed on before the servicing is triggered depends on which print mode is
selected:
Print Mode Selected
(Bidirectional)
Draft (2 passes) 18m/60ft
Normal (4 passes) 9m/30ft
High Quality (8 passes) 4.5m/15ft
High Quality 200% (16
passes)
Long prints (more than 10m/33ft) operation
Canceling the automatic servicing is not recommended. Over time, doing so
will negatively impact printhead performance and image quality.
As the nozzle plate accumulates ink from the tails of the drops of solvent ink,
and the accumulation of ink in the capping units, image quality starts to
deteriorate.

performed

The accumulation of ink on the nozzle plate creates "nozzle-outs" that can

Troubleshooting
result in banding on vinyl material, and color deviation on textiles.
Dirty nozzle plate due to lack of regular servicing
This problem can be resolved by stopping the printer and allowing it to
perform minimal printer maintenance.
Longer-term side effects can occur when frequently printing long plots. For
more details on long-term side effects, see Page 1-13.
How to correctly print frequent jobs of length longer than
10m/33ft
There are three different scenarios to consider:
1 The customer is printing individual jobs nested as one file. Printing in this
manner is not recommended because it puts unnecessary stress on the
printhead. The benefits of printing in this manner are likely to be offset by the
need re-print all or some parts of the printout.
2 The customer is printing large tiles. When printing large tiles, ensure that the
“Send tiles as independent job” setting is selected in the RIP. If it is not
selected, the RIP will send the tile as one job, which will not allow the printer
to perform servicing between the tiles.
3 The customer is printing single jobs that are longer than 10m/33 ft. When
printing jobs of this size, the printer requires resting periods, during which it
performs printhead servicing.
As a guideline, the default resting period is 10 seconds for every 10 meters
of printed media. The length of printed media per rest can be shortened or
lengthened based on the amount of ink applied during printing.
For more information on defining periodic printhead resting periods, see
Page 1-11. Be aware that printhead resting periods can result in unwanted
side effects such as banding. For more information on banding under these
circumstances, see Page 1-12.
1-10
With any of these three printing scenarios, there are other factors to consider
to ensure correct printhead functionality:
Ensure that the environmental temperature is above 20ºC/69ºF.
Ensure that the color stripe is set to ON.
HP Designjet 9000s Series Printer Service Manual
Troubleshooting
Ensure that the Central Platen Heater temperature is below 40ºC/104ºF.
Ensure that the arrow on the Fan Guard Lever is aligned with the edge of
the media, to avoid excessive hot air blowing on to the nozzle plate.
Select the “Send tiles as independent job” setting in the
Postershop RIP
Define a periodic printhead resting period
The printer has the following two settings:
1 #PH REST PERIOD: The setting defines how many print cycles are made
before the printer rests. One cycle equals one pass.
The recommendation is to allow the printer to rest every 10m/33 ft, but the
length must be converted into cycles based on the print mode.

2#PH REST TIME: This setting defines the amount of time (in seconds) that
the printer rests during each resting period.

Because the print mode is set to
NORMAL, there will be 1,100 cycles
per 10m/33ft of media printed. The
rest time is set to 10 seconds.
Banding while stopping
The previous recommendations will ensure the health of the printhead and
image quality, allowing results like that shown below.
However, side effects may occur when using the aforementioned settings.
The image below illustrates banding that can occur during the printer resting

periods.
This type of banding is not usually visible when viewed from a distance.
Depending on the media type and the printed image, the customer might
experience a slight color change in the image (banding) where the
printhead was positioned during the printer resting period. The banding is
most likely to occur when printing dark images on textiles.
Banding can be reduced by testing different rest times, but the main factor is
the type of media being printed on. Banding does not occur, for example,
when printing on HP Self-Adhesive Vinyl.
Possible long-term side effects
Failure to follow the printhead maintenance recommendations will result in
image-quality issues; the most significant and immediate of which being
banding or color shift in the middle of a print. However, long-term failure to
follow the maintenance recommendations will result in printhead damage.
To maintain the health of the nozzles, the printhead spits into the capping
units after every other pass. The ink accumulates in the capping units until
printhead servicing, at which time they are emptied.
If printhead servicing is not done during the printing of long prints, two
unwanted scenarios can occur.
1 The Printhead Nozzle Plate can come in contact with the ink while printing,

1-13
Troubleshooting
Ink overflow
resulting in nozzle blockage.
2 The ink in the capping units can overflow. When this occurs, the ink seeps
below the capping units where it dries and accumulates. Under these
circumstances the printer is not able to adequately perform the capping and
priming procedures. Over time, the nozzles become blocked.
Dry ink below capping units
To verify that the capping units are working correctly, follow these steps:
1 Perform the PH WASH procedure.
2 Turn the printer off by using the hard ON/OFF switch at the front of the
printer, below the front heater.
3 Remove the covers to access the capping station.
4 Manually lower the capping station.
5 The capping units should not be empty. If any of the capping units are
empty, they are not functioning correctly.
Dry ink below capping units
If the capping units are not functioning correctly, the entire capping station
must be replaced. Adequate maintenance practices are the best way to
assure maximum printhead life and image quality.

Self-Diagnostic Errors at Power On
When the Printer is powered up, it performs the Boot-Up sequence which
initializes the major components of the Printer. If for some reason the BootUp sequence fails because a component has failed to initialize, an error
code will appear on the Front Panel.
