specific level.
The fixing temperature has dropped to an
abnormally low level.

T-9-3
When each of the following conditions is detected for 200 msec or more continuously, the
machine assumes that an error has occurred.
- A temperature of less than 30 deg C is detected by the fixing thermistor after 1 sec since the
start of power supply.
- A temperature of less than 70 deg C is detected by the fixing thermistor after 2 sec since the
start of power supply.
- A temperature of less than 120 deg C is detected by the fixing thermistor after 6 sec since
the start of power supply.
The fixing thermistor detects 250 deg C or more for 200 msec or more continuously.
A hardware circuit detects overheating in relation to the fixing thermistor (main/sub).
The fixing thermistor detects 295 deg C or more for 200 msec or more continuously.
In the course of start-up control, the fixing thermistor detects less than 115 deg C for 400 msec
or more continuously after 1.3 sec since it detected 100 deg C. Or, the fixing thermistor
detects less than 150 deg C for 400 msec or more continuously after 1.3 sec since it detected
140 deg C.
In the course of normal temperature control, the fixing thermistor detects less than 140 deg C
for 200 msec or more continuously.
Missing of the connector is detected for 30 msec continuously.
The reading of the fixing main thermistor is in excess of 100 deg C with the fixing motor in
a locked state and, in addition, the machine fails to detect the marker signal for 6 sec.
The locked status is not detected even when 2 sec elapses after the motor is turned on.
The motor is unlocked for 500 msec continuously after the locked status is detected.
