Phaser 3140/3155/3160 Printer Service Manual 2-9
Theory of Operation
Fuser
The Fuser consists of a Halogen Lamp, Heat Roller, Pressure Roller, Thermistor, and
Thermostat. The Heat Roller transfers heat from the lamp to the paper. The
Pressure Roller adheres the melted toner to the media surface. The Thermistor and
Thermostat monitor Fuser operating temperature.
Halogen Lamp
•Voltage
• 120V: 115 V ± 5%
• 220V: 230 V ± 5%
• Capacity: 750 Watt ± 25 W
Thermistor
The Thermistor detects the temperature of the heating unit and feeds the data to
the main processor.
Thermostat
When the Heat Lamp becomes too hot, the Thermostat cuts off power to the lamp
to prevent 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, the 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.
