Troubleshooting
Which Firmware relates to which Ink system?
A.01.XX This firmware revision means that the Printer can only use Imaging Inks.
A.02.XX This firmware revision means that the Printer can use both the Imaging Inks and
the new UV Durable Inks.
Use theLatest Firmware/ PostScript Revision
Always check which firmware revision the printer is using (Utilities / Statistics / Code Rev)
and if necessary, update it. Also check the PostScript revision (Utilities / Statistics / PostScript
Rev) and if necessary, update it.
Install theFirmwareSIMM and PostScript SIMM in thecorrect slots
Remember that the Firmware SIMM (including the firmware code for the imaging and UV
Durable Inks) must installed in the first slot from the left. The PostScript SIMM must be
installed in the second slot from the left.
Perform a Service Test on the Failed Component/Assembly
Always perform a Service Test on the component/assembly that you are about to replace, just
to make sure that is the component/assembly that has failed. If thetest on that
component/assembly passes, do NOT replace it.
Solving ImageQuality Problems
Whenever an Image Quality problem appears, print the Image Quality Print to help diagnose the
problem. The Image Quality Print will help you differentiate between possible IDS / Printer /
media errors and other problems such as incorrect front panel selection, driver or RIP
configuration or mechanical problems. For information on solving Image Quality problems '
Users Guide.
Line Sensor has Problems Detecting Media
Clean the drive roller. Replace the lens cover ' Users Guide, Chapter 10 (Lens Maintenance).
Perform the Line Sensor calibration. Reinstall or, if necessary, replace the Line Sensor.
Carriageis Noisy
Clean and apply lubricant to the Carriage slider rods. Perform Carriage Axis Test.
Service Station is Noisy
Clean and apply lubricant to the Service Station slider rod. Perform Service Station Test.
Printer continuously rejects Printheads
Clean Printhead and Carriage flex contacts. Remove all Printheads from the Carriage and try
installing just the rejected Printhead. If the Printhead is still rejected then replace the
Printhead with a new one. If the new Printhead is not rejected then check, one by one, if the
other Printheads are also rejected. Perform the Printhead Continuity Test. Perform the
Electronics Test. Replace the Trailing Cable. Replace the Carriage Assembly.
Bail Assembly does not lower all the way
Check that there are no obstructions in the way of the Bail Assembly. Perform the Bail Test.
Cover Sensors aren't Working
Check if the faulty sensor is installed correctly. Check if the cable for the faulty sensor is
connected correctly. Replace the faulty Sensor.

Media continuously crashes
Check if the media loaded is HP approved. If the media is not HP approved, advise the
customer to use HP media and check to see if the problem is now solved. Perform the Refill
Calibration and try to load the media again. Replace the Overdrive Assembly. Remove the
Drive Roller and install in the correct position.
Switch Power Off / Check Printhead Path" message appears when the Printer is
about to cut or is cutting?
Check the media path and clear it if necessary. Perform the Cutter Test. Replace the Cutter
Assembly. Replace the Overdrive Assembly.
Lens Maintenance" message appears on the Front Panel?
The lens cover, which is installed on the line sensor, is dirty. Clean the Mark Encoder on the
Driver Roller. Replace the lens cover ' Users Guide, Chapter 10 (Lens Maintenance).
Printer does not Power ON
Check that the power cord is connected correctly. Check that the Flash SIMM is installed
correctly in the correct slot (the first slot from the left) at the back of the Printer. Try to
disconnect all the cables, apart from the Front Panel Cable, from the Electronics Module and
then try to power ON the Printer again. If nothing appears on the front panel display, then
replace the Electronics Module. If the Printer does Power On with the cables disconnected,
then the problem must be with another component of the Printer. To find the faulty
component, power OFF the Printer and connect one of the cables and power ON again. Once
the faulty component is connected, it will not allow the Printer to power ON. This component
should then be replaced.
Printer has problems with Media Loading
Check that the Media Sensor is installed correctly. Check if the cable for the Media Sensor is
connected correctly. Check if the Pincharms are down (the Pincharm lever should be up).
Make sure Line Sensor is installed correctly. If necessary, replace Line Sensor. Replace Media
Sensor. Perform Electronics Test.

D12. Image Quality
Purpose Test the image quality attributes of the printer.
If after aligning the Printheads, Bad Printhead Alignment" is displayed Try recovering the
printheads using the front panel menu. Check the alignment pattern to check if any of the
colors are printed badly. If a color is printing badly then replace the complete Ink Delivery
System of the color that is bad. Perform the Line Sensor calibration. Replace the lens cover '
Users Guide, Chapter 10 (Lens Maintenance). Check if the Line Sensor is installed/connected
correctly. Perform the Line Sensor Test. Perform the Electronics Test.
If the values of the Printheads are between -1.0 and +1.0 for any of the Printheads then
the test has passed.
If the values of the Printheads are NOT between -1.0 and +1.0 for any of the Printheads
then the test has failed Perform the Printhead Alignment Calibration. Perform the Line
Sensor calibration. Replace the lens cover ' Users Guide, Chapter 10 (Lens Maintenance).
Perform the Electronics test. Check if the Media used is suitable for the printer. Check if the
Line Sensor is installed/connected correctly. Replace the Line Sensor.
D13. Printhead ID
Purpose Check the default settings of the printheads. ID 200000 is for inks for imaging and
ID 220000 is for UV Durable Inks.
This test is for information only which might be requested in the event of an escalation.
D14. Printhead Continuity
Purpose Check the primitives and address maps of the printheads.
The values shown for all Printheads should be 0. If a different value is shown then that
Printhead has a continuity problem. Try the following:
1 DO NOT replace any parts. This will cause extra problems. Remove the
Printheads and clean the flex contacts on the Carriage and the Printheads. Reseat the
Printheads and try the test again.
2 Even if one of the Printheads failed the Printhead Continuity test, you must remove all the
Printheads from the Carriage and try installing them one by one. Before installing each
Printhead, check the continuity of all four Printheads. The front panel should display a
3ffff / 3fff result for each Printhead that is not inserted and the original values (the value
that was displayed before the Printhead was removed) for the Printheads when they are
inserted. If you get a value that is different than 3ffff / 3fff when the Printheads are
removed then you must perform step 1 again. If you get the same results after repeating
step 1, then the carriage is damaged. Replace the Carriage Assembly. When you insert each
Printhead, the values should change only for that Printhead. If the values of other
Printheads also change, then the problem is the Printhead itself and not the actual Printer.
In this case you must replace the complete Ink Delivery System of the color that failed.
3 If you continue getting the original value (the value that was displayed before the
Printhead was first removed) then you must replace the complete Ink Delivery System of
the color that failed and try the test again.
4 As a last resort, replace Carriage Assembly.
D15. Clean Roller
Purpose To rotate the Drive Roller when it requires cleaning.

Purpose To reset the internal counters.
If D1700 OK" Counters reset correctly.
If D1701 Fail" Replace Electronics Module.
D19. HardDisk Drive Revision
Purpose To show the revision of the internal Hard Disk Drive.
