Fuser Service Check

Cold Fuser Service Check
Error codes 920, 921, and 922 may display for a cold fuser failure. A
920 error caused by low line voltage can sometimes be cleared by
turning the machine off and then on again. A 925 service error
indicates the wrong fuser lamp is installed. Be sure the correct type
of fuser lamp is installed in the printer.
If the correct lamp is installed and a 925 error remains, the problem
may be due to the following:
•
The fuser may have reached standby temperature too quickly.
•
The line voltage may be above the maximum rating for the
printer.
Note: A 920, 921 or 922 fuser error may be caused by an
incorrectly mounted thermistor.
Service Tip: Set the Fuser Temperature to NORMAL before starting
this service check.
