Theory of Operation
The following figure shows how the Heat Roller and belt compress the paper
and applied toner to fuse the image to the media.
Fuser Assembly Components
Component Function
Heat Roller The Heat Roller is a metal tube with a coated surface and a
Heater Assembly inside. As paper passes between the Heat
Roller and Pressure Roller, the heat fuses the toner to the paper.
Belt The Belt maintains pressure on the paper passing between it
and the Heat Roller. Pressure bonds the melted toner to the
paper.
Heater Lamps The Heater Rods are glass tubes containing heater coils. The
Main Heater Rod heats the entire length of the Heat Roller, and
the Dual Sub-Heater Rods heat the center.
Fuser Exit Roller Transports media out of the Fuser.
Non-Contact
Sensor
This sensor detects the center temperature of the Heat Roller.
Thermistors These sensors monitor the Heat Roller outside edge
temperature.
Thermostat The Thermostat provides a second-level of protection. If the
Heat Roller temperature exceeds the preset temperature, the
Thermostat cuts off the AC power to the Heater Lamps.
CRUM Maintains Fuser usage information.
Fuser Exit Sensor This sensor detects paper at the exit area behind the Fuser.
When paper is present, the signal /EXIT is Low.
