4–3Troubleshooting
Introduction
This chapter contains procedures for troubleshooting printer malfunctions.
Diagnostic test procedures are also covered in this chapter. Basic printer
operation is not covered. Since you must operate the printer to check its
performance, have the Operator’s Guide or User’s Manual at the printer site.
Fault Messages
This section contains troubleshooting tables for fault messages that can
appear on the Liquid Crystal Display (LCD) of the control panel.
The LCD can display two kinds of faults:
1. Operator correctable faults.
2. Faults requiring the attention of a field service technician. This type of
fault message can appear in two forms:
On some models, this type of message is indicated by an asterisk (*)
after the fault message.
On IPDS–capable models, this type of message is indicated by the
phrase PRINTER HALTED.
IMPORTANT
Test printer operation after each corrective action you take, and stop
troubleshooting as soon as the symptom disappears. Always press the
control panel switch that clears messages after you correct a fault.
