6) Thermostat

Thermostats cut off the power supply to the halogen lamp by opening the circuit when the heat roller becomes

abnormally hot as a result of problems such as NC sensor malfunction. These thermostats are used to prevent abnormal

operation. When the thermostat is triggered, it must be replaced (as well as the other damaged parts in the fuser unit).
