3–2 Troubleshooting
Introduction
This chapter contains procedures for troubleshooting printer malfunctions.
Diagnostic test procedures are covered in this chapter, but basic printer
operation is not covered. Since you must operate the printer to check its
performance, have the Operator‘s Guide at the printer site.
Fault Messages
This section lists the fault messages that can appear on the control panel
display. The messages are listed in alphabetical order, followed by a
troubleshooting table.
If a fault condition occurs in the printer, the status lamps on the control panel
flash on and off and the first line of the display indicates “Fault Condition.”
The second line of the display indicates the specific fault.
There are two types of displayed faults:
• Operator correctable
• Field–service required, indicated by an asterisk (*) next to the fault
message
IMPORTANT
Test the printer after each corrective action. Stop maintenance when the
symptom disappears. Always press the CLEAR switch after correcting a
fault indicated by a fault message.
