2) Remove and disassemble the fuser unit.
(
Refer to 3.3.23 Fuser Unit
)
3) Measure the resistance value of the thermistor (
1404-001453
). If the measured value is out of 307KΩ~430KΩ
@25
℃
, replace the thermistor.
4) Install the fuser unit after replacing the thermistor.
5) If the error persists, replace the fuser unit (
