0001 When the detected temperature of the Main Thermistor fails to reach the
specified temperature at temperature rising control.
Required
E001 Error in overheating of Fixing Assembly
0000 When the Main Thermistor detects 250 deg C or higher for consecutive
200msec or longer.
Required
0001 When the hardware circuit detects overheating of the Main Thermistor or
Sub Thermistor for 30msec or longer.
Required
0002 When the Sub Thermistor detects 295 deg C or higher for consecutive
200msec or longer.
Required
E002 Error in temperature rising of Fixing Assembly
0000 1. When the Main Thermistor detected a temperature lower than 115 deg C
for consecutive 400msec or longer after 6 seconds that the Main Thermistor
detected 100 deg C
2. When the Main Thermistor detected a temperature lower than 150
deg C for consecutive 400msec or longer after 6.0 seconds that the Main
Thermistor detected 140 deg C
Required
E003 Detection of low temperature
0000 When the Main Thermistor detects lower than 140 deg C for consecutive
400msec or longer.

0000 When removal of the connector (J214) is detected for consecutive 30msec. Not
required
E014 Error in rotation of Fixing Motor (M1)
0001 Detection is performed every 100msec since the start of drive and there has
been no lock detection signal in 2sec.
Not
required
0002 Detection is performed every 100msec during the drive (after the lock
detection) and the lock signal has not detected for 5 times consecutively (in
500msec).
Not
required
0003 When the Fixing Pressure Release Sensor never detected pressure release
during the 3 seconds while the fixing pressure was released
Not
required
0004 When the Fixing Pressure Release Sensor never detected pressure during
the 3 seconds while the fixing pressure was applied
Not
required
