Title
The temperature detected by the main thermistor does not rise to the speci-
fied value during startup control.
The reading of the main thermistor is 250 deg C or more continuously for 200
msec.
The hardware circuit detects overheating of the main or sub thermistor for
200 msec.
The reading of the sub thermistor is 295 deg C or more continuously for 200
msec.
1. 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.
2. 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.
The reading of the main thermistor is less than 140 deg C continuously for
400 msec or more.
When disconnection is detected with connector (J214) for 30 sec continu-
ously.
When the Fixing Pressure Release Sensor never detected pressure for 1.5
sec.
When the Fixing Pressure Release Sensor never detected pressure release
for 1.5 sec.
Detection is executed every 100 msec after the start of motor rotation; how-
ever, the drive detection signal is absent for 2 sec.
During motor rotation, detection is executed every 100 msec; however, the
drive signal is absent 5 times in sequence.
Zero Cross failed to be detected for 500ms or more while the relay was ON.
* The same condition is detected after the error retry is performed.
