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 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.
