Fuser Unit Drive - Samsung SL-X7600GX Service Manual

2. Product Specifications and Description
4) Thermistor (NC sensor)
The temperature of the fusing belt is monitored by NC sensors (non-contact type thermistors) located near the center and
the end of the fusing belt.
5) Thermostat
Thermostats cut off the power supply to the halogen lamp by opening the circuit when the fusing belt 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).

The fuser motor[A] drives the pressure roller[B] through the gear train. The fusing belt[C] pressurized by the pressure
roller[B] is rotated by driving it.
