(6) Fuser
The toner image transferred on the paper is fused on the paper by heat and pressure when
the paper passes through the heat roller and backup roller.
The Teflon coated heat roller is heated by a 800W or 350W internal halogen lamp, and
backup roller is heated by a 50W internal halogen lamp. The fuser temperature is controlled
according to the sum of the temperature that is not contacted with the thermistor ground
against the heat roller surface and the temperature that is detected with the thermistor
ground on the backup roller surface. There is also a thermostat for safety purposes. When
the heat roller temperature rises above a certain temperature, the thermostat opens and
shuts down the power supplied to the heater. The backup roller unit is pressed against the
heater with a press spring on both sides.
(7) Cleaning

ferred to the paper, then the disposal toner of the disposal toner box is collected at the
rear.
(8) Cleaning
The cleaning blade scrapes off residual toner on the transfer belt then collects is in the
disposal toner box of the transfer belt unit.
