Action

Fuser Lamp
Remove the controller board and run
the Cooling Fan Test in the
Hardware Test Mode. Observe the
lamp through the left side frame. If
the lamp doesn’t come on, unplug
the printer and check the continuity
between the two pins on the fuser
lamp cable going to the fuser
assembly. If you do not measure
continuity, remove the fuser
assembly and check the continuity of
the lamp. If incorrect, replace the
lamp. If correct, replace the contact
in the fuser cover.
2
LVPS
Turn the printer off. Disconnect the
fuser lamp connectors at the fuser
assembly. Turn the printer on and
check across the cable for line
voltage. If incorrect, remove the
LVPS and check both F1 and F2
fuses. Remove the LVPS from the
printer. Replace any open fuses and
attach the power cord. If the fuses
open, replace the LVPS. If the fuses
open after the lamp cables are
connected to the fuser, the fuser
lamp circuit is shorted. Inspect the
fuser lamp contacts in the fuser
cover. Replace the contacts as
necessary.

Thermistor
Disconnect the thermistor cable from
the engine board. The resistance is
as follows:
HOT - 1K ohms
COLD = 150K ohms to 475K ohms
