Guide to Troubleshooting the Printer
Introduction
This chapter will guide you through the relevant steps to take when troubleshooting the Printer.
Troubleshooting System Error Codes
Chapter 2 - System Error Codes contains a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if the error code has disappeared.
If you have an error code which is not documented in this Service Manual or you have an error which you cannot resolve, then report the error to the HP Response Center or the nearest HP Support Office. When reporting the error, have the following information ready:
Model and Serial Number of the printer.
Which firmware revision the printer is using.
The complete error number.
The System and History Prints
Which software application the customer is using (name, version, etc.).
.
Whenever an Error Message is displayed, you should try to switch the Printer Off and then On again to see if the error disappears. If the error disappears, there is no need to troubleshoot the Printer any further.
Performing a Service Test on a Failed Assembly
If possible, always perform a Service Test on the component/assembly that you are about to replace, just to make sure that is the actual component/ assembly that has failed.
If the test on that component/assembly passes, you should NOT replace it.
For information on the Service Tests and how to use them see Chapter 4 - Maintenance Mode.

Problems with Media End/Slack and TUR Sensors
If you see the following behavior when operating the Printer, it could be due to the incorrect installation of the Media End/Slack and TUR Sensors:
1 On the Media Load side:
During media loading, when the Printer performs the slack check, the
printer continues to ask you to check the Slack.
If during media load, the media slack was too high, then at the end of the
media loading process, the Printer will display "End of Media" on the Front Panel.
2 On the TUR side:
The Take-Up-Reel will not rotate.
In all these situations, you should double check that the Sensors have been installed and connected correctly

Troubleshooting
Solving Media Skew and Differential Banding Problems
The following information is not intended to be an exhaustive description of the media loading process, but a list of the critical parts of the loading process in order to avoid the following problems:
Media skew: when the media shifts from right to left or vice versa. This is
mainly visible when the vertical section of the media on the input side is ‘bending and flexing’, or when the media rolls incorrectly onto the Take­Up Reel.
Differential banding: when the banding is different from the right side to
the left side through the carriage movement.
1 Ensure that the roll of media is correctly loaded onto the Take-Up Reel and
the Main Scroller. This can be verified with the customer over the phone.
See the loading-guide table below for recommended settings to assist when printing in the following methods:

Troubleshooting
a Ensure that the core of the media is correctly fixed onto the Main Scroller.
To lock the media roll to the main scroller, turn the hand-wheel (1) of the main scroller clockwise until it reaches the stop. This must also be done for the Take-Up Reel if it is used.
Use the Media Positioning Tool shown in the picture below to leave additional space between the media roll and the drive wheel. This will help to position the flange on the TUR side.
b Ensure that the toothed flange spacer (1) is correctly inserted on the left
side of the roll on the Main Scroller (2). This must also be done for the Take-Up Reel if it is used.
If the toothed flange spacer is not inserted correctly, the core of the media will not rotate in a circular motion, but will rotate in an elliptical motion, which will result in media skew.
HP Designjet 10000s Series Printer Service Manual
1-13
Troubleshooting
c Ensure that the locking knob (3) is fully tightened on the flange stopper
(2) to lock it to the flange spacer (1) and the main scroller. This must also be done on the Take-Up Reel if it is used.
2 During the loading process of the media, ensure that the media is correctly
wound into the roll.
a Use the black media advance switch at the front of the printer to feed the
media through the media feeder until it almost reaches the floor. Do not close the Media Lever yet.
1-14
b Use the white rewind switch at the front of the printer to rewind the media
(1) until it is just protruding from the rear cover.
HP Designjet 10000s Series Printer Service Manual
Troubleshooting
c Lower the Media Lever and follow the instruction from the Front Panel.
3 Ensure that the media is tightly rewound onto the roll.
If the media (1) is not correctly rewound onto the roll as explained in step 2b, do not use the roll. The probability of skew will be very high if you choose to continue. You can repeat steps 2a - 2c to get the roll to load straight and parallel with the ends of the cardboard core.
After rewinding the media, verify that the media is correctly re­wound onto the Main Scroller. If the edge of the core of the me­dia (1) is not straight, as shown in the picture, this will generate skew.

Troubleshooting
4 Ensure that the correct length of tension bar is being used in the slack area
of the media.
The tension bar must be half the width of the media. If the tension bar is too big or too small it can create skew. Make sure the tension bar (1) is positioned in the center of the slack area of the media or the media may not feed smoothly.
When using PVC (Vinyl), it is recommended that you use a short tension bar (16”, 40cm).
5 Ensure that the Edge Guards (1) are correctly installed.
1-16
6 When using the Take-Up Reel, ensure that the correct process is being
performed.
a When taping the media onto the Take-Up Reel, take the following points
into consideration:
Ensure that the media is advanced towards the empty core by using the
feed entry from the Front Panel (the Media Load Lever should be closed. The media must remain fully loaded).
Ensure that the media is straight.Ensure that you first tape the middle of the media to the core, and then
tape from the inside, until you reach the outside edges of the media.
Do not create any additional tension on the media when you are taping.
HP Designjet 10000s Series Printer Service Manual
Troubleshooting
Carefully apply the tape to the media and core.
b Use the Front Panel Feed Menu to feed more media.
c Manually turn the Take-Up Reel a few times. This is not mentioned in the
user's guide, but should be noted. This is done to ensure that no lengths of tape fall off, which could create skew.
d Ensure that the correct flanges are used for the loaded media. For most
media (with the exception of film), the small flanges can be used. Using the big flanges on some media can cause skew. The tension bar (1) should be placed on the tension bar guides (2).

e Use the O-rings (2) to maintain the flanges on the Take-Up Reel.
f When using PVC media (1), taking the following points into
consideration will help to reduce skew:
Use the large, black Media Tube Flanges on the Take-Up Reel.Do not put the tension bar on the tension-bar guides.Use the tension bar without flanges (2) or try removing it to see if it
reduces the skew.
Adjust the length of the tension bar to approximately half the width of the
media, and then position it in the slack area as shown below.

When using PVC (Vinyl), it is recommended that you use a short tension bar (16”, 40cm).
7 Use the dryer to dry the media before it is wound onto the Take-Up Reel.
Images printed with a lot of ink take longer to dry and can cause the Take­Up Reel core to stick, putting unwanted tension on the media. Using the dryer will help to keep the printed media from sticking to the core and will help to reduce skew.
8 Verify the position of the Media-Pressure Lever.
Verify the position of the Media-Pressure Lever on the right side of the printer. By default it should be in the lowered position, which adds pressure to the media. However, for certain media, such as textile media, the Media­Pressure Lever should be set at the raised position, which reduces pressure

To know if the Take-Up Reel is generating skew, try printing without the Take­Up Reel. If there is no skew, focus must be placed on how to set-up media on the Take-Up Reel.
If the case can not be solved through the phone call, the follow­ing must be performed by an ‘On site customer engineer’.

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.
