1. Thermostat
When a heat lamp is overheated, a Thermostat cuts off the main power to prevent over-heating.
- Non-Cotact type Thermostat
2. Fuser Belt
The fuser belt transfers the heat from the lamp to apply a heat on the paper.
The surface of the fuser belt is coated with Teflon, so toner does not stick to the surface.
3. Pressure roller
A pressure roller mounted under a heat roller is made of a silicon resin, and the surface also is coated with
Teflon. When a paper passes between a heat roller and a pressure roller, toner adheres to the surface of a
paper permanently.
