System Error Codes
System error codes may be displayed on the front panel display. They are recorded at parameter locations 176 through
179. Printing the Stored Parameter Report from the Service and Factory Menu will provide a printed copy of all the
parameter values. Individual parameter values may be viewed using the Changes Stored Parameters feature also in the
Service and Factory Menu.
The error codes are recorded sequentially starting at parameter location 176. If more than four system errors have
occurred, the previously recorded error codes will be overwritten in a wrap-around manner. In this case, the last four
error codes will be known but the last error that occurred cannot be determined.
Refer to the following table for a description of the system error codes and recommended actions. Replacement of the
Main PCA, LIU, scanner parts, and print mechanism should be referred to the HP Customer Support Center for repair
arrangements. Do not attempt to repair the unit.
