13.4.5 Temperature detection section
To maintain the fuser roller at a constant temperature, the two fuser roller thermistors (front and rear)
detect the fuser roller temperature and control the on/off of the IH coil. The abnormal temperature of the
IH coil is detected by the three fuser roller thermistors (front, center and rear), while that of the pressure
roller is detected by the pressure roller thermistor.
1. Relation between the thermistor output voltage and surface temperature of the fuser roller
2. Control of the surface temperature of the fuser roller
