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 in the printer and does not
match the one stored in the printer code.
Service Tip: Set the Fuser Temperature to NORMAL before starting
this service check.

+5 V dc (static) 0 V dc (fan running).
If incorrect, replace the main fan. If
this does not fix the problem, replace
the engine board.

engine board. The voltages are as
follows:
+22 V dc to +24 V dc
