Canon image runner Detecting Errors

The system used to control the fixing temperature checks for the following errors:
1. Temperature error by the main thermistor (TH1)
2. Sensor error by the sub thermistor (TH2)
3. Overheating error by the thermal switch (TP1)

The control system makes use of the following signals:
[1] Fixing roller temperature detection signal 1; generates a voltage suited to the temperature
detected by the main thermistor.
[2] Fixing roller temperature detection signal 2; generates a voltage suited to the temperature
detected by the sub thermistor.
[3] Sub heater drive signal; when ‘1’, the sub heater turns on.
[4] Sub heater temperature detection signal; when the sub heater is supplied with power,
‘0’.
[5] Main heater drive signal; when ‘1’, the main heater turns on.
[6] Main heater temperature detection signal; when the main heater is supplied with
power, ‘0’.
