0000
Description
When 1 sec passed after energization of the heater, the detected temperature of
the main thermistor is not 5 deg C or more (0 deg C at power on).
Cause
Disconnection of main thermistor, disconnection of fixing heater, error in DC
controller PCB.
- Check of the connector of the low-voltage power supply PCB
- Replacement of fixing film unit
- Replacement of DC controller PCB
E001
Error in overheating of fixing assembly
0000
Description
The status where the detected temperature of the main thermistor is 225 deg C
(approx. 0.84V equivalent) or more is detected for 0.5 continuous sec or more.
Cause
Error in main thermistor, error in DC controller PCB.
- Check of the connector of the low-voltage power supply PCB
- Replacement of fixing film unit
- Replacement of DC controller PCB
0001
Description
The status where the detected temperature of the sub thermistor is 245 deg C
(approx. 2.12V equivalent) or more is detected for 0.5 continuous sec or more.
Cause
Error in sub thermistor, error in DC controller PCB.
E003
Error in abnormally low temperature of fixing assembly
0000
Description
The status where the detected temperature of the main thermistor is 100 deg C
(approx. 2.60V equivalent) or less is detected for 0.5 continuous sec or more.
Cause
Error in low-voltage power supply PCB, disconnection of main thermistor, error
in DC controller PCB.
- Replacement of low-voltage power supply PCB
- Replacement of fixing film unit
- Replacement of DC controller PCB
0001
Description
The status where the detected temperature of the sub thermistor is less than 100
deg C (approx. 0.38V equivalent) is detected 0.5 continuous sec or more after
energization of the heater.
Cause
Error in sub thermistor, error in DC controller PCB.
- Check of the connector of the low-voltage power supply PCB
- Replacement of fixing film unit
- Replacement of DC controller PCB
E004
Error in fixing power supply drive circuit
0000
Description
Cannot detect the zero cross signal for the specified period or more.
Cause
Error in fixing control circuit block.
- Replacement of low-voltage power supply PCB
E012
