Thermostat, heater Heater of the fuser unit is controlled of its
temperature. Check if the fuser unit gets hot or
not by touching it with hands.
If the fuser unit temperature does not increase
and remains cold, check that the resistance
between pin-1 and pin-4 and between pin-3 and
pin-4 is about 4 to 7
Ω
, between pin-1 and pin-
2 and between pin-3 and pin-2 is about 1 to 3
Ω
respectively. (Refer to section 6.3 Resistance
value (fuser unit).)
Replace the fuser
unit.
