Turn the printer off and disconnect
the fuser lamp wires from the fuser.
Check for continuity across the fuser
lamp wire contacts. If there is
continuity, go to step 1: Continuity.
If there is no continuity, go to
step 2: No Continuity.
Step 1: Continuity
Measure the voltage at connector
CN502 on the LVPS. It should match
the line voltage. If it does not,
replace the LVPS. If line voltage is
present, check the fuser lamp cable
for continuity. Replace if
defective.Make sure the fuser
thermistor is correctly connected to
CN10 on the engine board. If the
problem persists, disconnect the
thermistor cable from CN1o on the
engine board and measure the
voltage between CN10-1 and
ground. The voltage measures
approximately 3.9 V dc. If the voltage
is incorrect, replace the engine
board. If correct, replace the
thermistor.
Step 2: No Continuity
Check the thermal fuse for continuity.
If incorrect, replace the thermal fuse.
If correct, replace the lamp.
