Fuser unit error
1.
Does the error occur immediately after the printer is turned on? Replace the
fuser.
2.
Check that AC voltage supplied to the printer is correct.
3.
Does the fuser get hot? If not, replace the fuser.
4.
If the fuser does warm up, verify that it is reaching the correct temperature
by running the service test “Switch scan test” on page 63.
5.
Does AC voltage appear between Pins 1 and 2 of CN 4-1 and CN 4-2 of the
fuser connector. These pins connect to Pins A and B of the fuser (illustrated
below) when the fuser is installed. Remove the fuser to check. If not,
replace the power supply.
Bear in mind that the correct AC voltage may be present at Pins 1 and 2 of
CN 4-1 and CN 4-2 even though the drivers feeding these pins are damaged
and cannot deliver the current required by the fuser heaters.
6.
Replace the engine controller board.
7.
Replace the low-voltage power supply.
