CHAPTER 6 FIXING SYSTEM
6-1
I. OUTLINE OF OPERATIONS
A. Outline
The pressure roller in the fixing assembly is driven by the main motor (M1).
The rotation of the pressure roller causes the fixing film to rotate.
Some sections of the underside of the fixing film is heated by the fixing heater.
The temperature of the fixing heater is monitored by the thermistor (TH1), and the
readings are sent to the microprocessor on the DC controller/DC power supply circuit in
the form of the fixing heater temperature sensor signal (TH1).
Based on the signal, the microprocessor of the DC controller/DC power supply
circuit controls the temperature of the fixing heater by the fixing heater drive command
(HTRD).
