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