The ceramic heater fixing method is adopted on the fixing assembly of this machine.
Temperature control of the fixing assembly is performed by the fixing control circuit and the fixing heater safety circuit according to the commands from CPU
(IC1001) on DC controller PCB.
Fixing heater (H1)
A ceramic heater for heating the fixing sleeve. The heater has one piece of U-shaped heating element that practically works as 2 heaters.
Thermistors (TH1, TH2)
Thermistors for detecting the fixing temperature. The following 2 types are used.
- Fixing main thermistor (TH1): contact type thermistor for detecting the fixing sleeve temperature that is located at the center inside the fixing sleeve.
- Fixing sub thermistor (TH2): contact type thermistor for detecting the fixing heater temperature that is located at the left edge of the fixing heater.
Fixing thermal switch (TP1A)
Non-contact type thermal switch for preventing the fixing heater from overheating that is located at the center of the fixing heater. When the fixing heater overheats,
the contact point opens and power to the fixing heater is cut.
