The fixing heater is equipped with 2 thermistor: a main thermistor in the middle and a sub thermistor at the end. The main thermistor is used to control the temper-

ature of the fixing heater and to detect its overheating, while the sub thermistor is used to detect an error temperature on the end of the fixing heater.

The CPU on the DC controller PCB monitors the main thermistor signal (FSRTH) and the sub thermistor signal (SUBTH) from the thermistors for control of the

fixing heater drive signal (FSRD0) and the relay drive signal (RLYD), thus varying the supply of power to the heater and, ultimately, controlling the temperature

of the fixing heater.

2.Paper-present section temperature control

The fixing heater temperature is adjusted to the target paper-present section temperature according to the combination of the paper size, number of sheets fed, fixing

mode, and temperature detected by the fixing main thermistor.

3.Sheet-to-sheet temperature control

The fixing heater temperature is held relatively below the target paper-present section temperature to prevent the paper-absent section temperature from rising be-

tween sheets.
