If the fuser lamp comes on and a
fuser failure light error code displays,
be sure the thermistor is contacting
the hot roll and the thermistor cable
is firmly seated in connector J7 on
the engine board (E320/E322) or
J14 on controller card
(E220/E321/E323).
Check for excessive toner buildup on
the surface of the thermistor. Clean
as necessary.
With the printer unplugged,
disconnect the thermistor cable from
J7 (engine board in E320/E322) or
J14 (controller card in
E220/E321/E323).
Measure the resistance of the
thermistor. The resistance measures
approximately 1K ohms immediately
after printing or POR to
approximately 240K ohms when
thermistor reaches room
temperature. (It may take 30 minutes
to cool.)
Replace the fuser assembly as
necessary.
