Regarding most common errors related to fixing section:

E000 The temperature of the fixing assembly is abnormally high.
0001 While startup control is under way, the reading of
the main thermistor is less than 30 deg C
continuously for 200 msec or more 1 sec after the
start of power supply.
While startup control is under way, the reading of
the main thermistor is less than 70 deg C
continuously for 200 msec or more 2 sec after the
start of power supply.
While startup control is under way, the reading of
the main thermistor is less than 120 deg C
continuously for 200 msec 6 sec after the start of
power supply.
The startup control does not end 30 sec after the
start of power supply.
Reset the condition in service mode:
COPIER>FUNCTION>CLEAR>ERR. Replace the
main thermistor. Replace the DC controller PCB

E001 The temperature of the fixing assembly is abnormally high.
0000 The reading of the main thermistor is 250 deg C
or more continuously for 200 msec.
0001 The hardware circuit detects overheating of the
main or sub thermistor for 200 msec.
0001 The hardware circuit detects overheating of the
main or sub thermistor for 200 msec.

Reset the condition in service mode: COPIER>FUNCTION>CLEAR>ERR. Replace the
main thermistor. Replace the DC controller PCB

E002 The rise in temperature of the fixing assembly is faulty.
0000 While startup control is under way, the reading of
the main thermistor is less than 115 deg C
continuously for 400 msec 1.3 sec after it has
indicated 100 deg C.
While startup control is under way, the reading of
the main thermistor is less than 150 deg C
continuously for 400 msec 1.3 sec after it has
indicated 140 deg C.
Reset the condition in service mode:
COPIER>FUNCTION>CLEAR>ERR. Replace the
main thermistor. Replace the DC controller PCB

E003 The fixing temperature is too low after a standby state.
0000 While regular temperature control is under way,
the reading of the main thermistor is less than 140
deg C continuously for 400 msec or more.
Reset the condition in service mode:
COPIER>FUNCTION>CLEAR>ERR. Replace the
main thermistor. Replace the DC controller PCB

E007 The rotation of the fixing film is faulty.
0000 While the fixing motor is rotating, the marker
signal is not detected for 6 sec with the reading of
the main thermistor indicating 100 deg C or more.
Reset the condition in service mode:
COPIER>FUNCTION>CLEAR>ERR. Replace the
main thermistor. Replace the DC controller PCB
REPLACE FIXING FILM ASSY(HEATER)
