50.x Fuser Error
(continued)
X Description:
1 Low temperature error
2 Fuser warm-up service
3 High fuser temperature
4 Faulty fuser
5 Fuser voltage mismatch (verify that you have
NOT installed a 110V fuser in a 220V printer or
vice-versa).
6 Fuser heater cutoff
7 Fuser motor malfunction (see recommended
action for 50.7 Fuser error)
Note
Closely inspect the mechanical linkage. The gears along the gear
“drive” path can bind the gears, which will prevent M1 from rotating.
50.7 FUSER ERROR
The fusing motor (M1) drives the fusing assembly, the paper transport
(web) assembly, ITB lift mechanism, transfer roller, transfer roller lift
mechanism, and the face down output delivery drive assembly. A 50.7
fuser error appears when PS6 detects no motion within the fuser.
Photosensor PS6 is the fusing unit pressure switch.
1 Power cycle the printer to try to clear the message.
2 Remove the left-side cover of the printer. Verify that the fusing
motor (M1) connector is seated firmly into J102 of the feed PCB.
3 Ensure that the connector at J110 of the feed PCB is firmly seated
(this connector contains the wiring for PS6, which provides fuser-
motion feedback).
Note
Closely inspect the mechanical linkage. The gears along the gear
“drive” path can bind the gears, which will prevent M1 from rotating.
