Major Functions

2-38
The Fuser fixes the toner image onto the sheet by heat and pressure and guides
the sheet into and out of the fixing position.
• Heat Roller
A metal roller that transfers heat to the sheet to fuse the toner particles onto
the sheet surface.
• Pressure Belt
A combination of a belt and a pressurizing system for pressing the sheet
against the heat roller.
• Heater Lamp
A heating-coil-enclosed lamp located inside the heat roller to heat its entire
length.
• Temperature Sensor (contact type)
A thermistor (temperature-responsive resistance) positioned in contact with
the heat roller to detect its surface temperature and regulate heat lamp
operation.
• Thermostat
A component connected in series with the power supply for the heat lamp.
Prevents the overheating of the heat roller by releasing the contacts when the
contact section has reached a certain temperature due to a overheating
failure.
• Fuser Exit Sensor
Detects whether the fused print has passed through the Fuser based on the
change of the actuator position. (Sheet passed: Sensor beam received.)
