Thermistor
The Thermistor detects the temperature of the heating unit and feeds the data
into the main processor.
Thermostat
When the Heat Lamp becomes too hot, the Thermostat cuts off power to the
lamp to prevent from overheating.
Heat Roller
The Heat Roller transfers heat from the lamp to the paper. As the paper
passes between the Heat Roller and Pressure Rollers, toner is melted and
permanently fixed to the paper. The surface of the Heat Roller is coated with
Teflon, so that toner does not stick to the surface.
Pressure Rollers
The Large and Small Pressure Rollers are made of a silicon resin and the
surface is coated with Teflon. When media passes between the Heat Roller
and the pressure rollers, toner is melted and permanently fixed to the surface
of the paper.
Safety Features
Several protection devices are used to prevent Fuser overheating:
■ Hardware cuts off Fuser power when overheating is detected.
■ Software cuts off Fuser power when overheating is detected.
■ Thermostat cuts off main power to the lamp.
Interlocks disable the Fuser, motors and Laser Unit.
■ Fuser power is cut off when the front cover is opened.
