General Troubleshooting
This chapter will guide you through the relevant steps to take when troubleshooting the printer.
Troubleshooting System Error Codes
System Error Codes on page 51 contains a list of system error codes and their respective descriptions
and recommended corrective actions. Try only one recommended action at a time and check whether
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 (See Note below). Check firmware in Utilities /
Statistics / Code rev.
●
The complete error number (See Note below).
●
The Service Configuration Print.
●
The Current configuration sheet.
●
Which software application the customer is using (name, version, etc.).
NOTE: When reporting the System Error Code, make sure that you supply the full Error Code and the
firmware version. Without this information, HP Support Personnel cannot help you.
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 component/assembly that has failed.
NOTE: 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
Diagnostics Menu on page 87.
Performing the Necessary Service Calibrations
Is the printer calibrated correctly after replacing a component? For information on the Service
Calibrations and how to use them see
Service Menu on page 121.
NOTE: Remember that certain Calibrations are required even if an Assembly has been disassembled
to gain access to another Assembly or Component.
