did u remove to inspect the unit

The surface temperature of the fixing heater is detected to control the fixing heater drive signal so that the fixing heater temperature becomes the target temperature.
The temperature of the fixing heater is detected by the thermistor (TH1/TH2) provided on the fixing heater. If the surface temperature rises, the resistance of the thermistor lowers and the voltage of the fixing heater temperature detection signal (M_TH/S_TH) also lowers.


E001=
0000 Fixing unit temperature rise detection (by main thermistor)
0001 Fixing unit temperature rise detection (by sub thermistor)

0000 = Abnormally high temperature (detected by main thermistor)
The main thermistor detected an abnormally high temperature (240 deg C) during temperature control.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.

0001 = Abnormally high temperature (detected by sub thermistor)
The sub thermistor detected an abnormally high temperature (295 deg C) during temperature control.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.
