C. 3rd stage: Thermostat protection
• If neither the soft protection nor hard protection can detect an abnormally high tempera-
ture due to a defective thermistor, the Heating Roller Thermostat (TS1) and Fusing Pres-
sure Roller Thermostat (TS2) operate at the specified temperature. This shuts down the
power supply to the Heating Roller Heater Lamp (H1) and Fusing Pressure Roller Heater
Lamp (H2), thus forcibly turning them OFF.
