Fuser (PL7.1.1)
The Fuser is a unit that fuses the complete toner image transferred on the sheet with the sheet by heat
and pressure. The Fuser consists of the following components.
• Heat Roller — A spouted metal Roller, which has the surface for giving heat to fuse toner on a
sheet covered by the tube.
• Pressure Belt — A belt contained the pressurization system inside. Paired up with the Heat Roller,
impresses toner on the sheet.
• Heater Lamp — A lamp that seals the heat coil as a heat source in the Heat Roller and that is
stored inside the Heat Roller. A heating element that heats up the Heat Roller.
• Center Temp. Sensor (contactless type) — A thermistor as an electric resistor that reacts
corresponding with temperature changes, located in the Hear Roller contactlessly, and detects the
surface temperature on the Heat Roller. Based on the temperature detected, controls ON (power
distribution: lighting) / OFF (Extinction).
• Rear Temp. Sensor (contact type) — A thermistor as an electric resistor that reacts corresponding
with temperature changes, located in contact with the Heat Roller, and detects the surface
temperature on the Heat Roller. Prevents the abnormally high temperature of the Heat Roller.
• Thermostat — Located in series with the power source of the Heater Lamp, and prevents the
secondary excess rise of temperature by the open interface when the temperature excess rise
preventions (primary) by Temp. Sensor (thermistor) fails and temperature on the interface part
reaches to a certain level.
• First Time Fuse — Resets page count on fuser installation.
