Description
Abnormal temperature rise of fixing subthermistor 1
(THM1-2) (circuit failure)
Fixing subthermistor 1 (THM1-2) sensed an abnormal
high temperature. (ASIC detection)
Check the detection temperature of the fixing sub
thermistor 1 (THM1-2) in service mode (COPIER>
DISPLAY> ANALOG> FIX-UE).
A. In case that the detection temperature is 250 degC
A-1. The cable of the fixing sub thermistor 1 is
caught -> replace the fixing belt unit
B. In case that the detection temperature is other than
250 degC
B-1. Location of the fixing main thermistor is
inappropriate -> replace the fixing belt unit
B-2. Replace the DC controller PCB
NOTE: After performing the above remedy work, go
through the following to clear the error: COPIER>
FUNCTION> CLEAR> ERR
