Finishing and Paper Exit
Fuser Unit
The Fuser Unit, consisting of the Fuser Lamp, Fuser Roller, Pressure Roller, Thermistor, and
Thermostat, bonds the toner into the paper using heat and pressure.
Fuser Lamp (314)
Located in the Fuser Roller is a Halogen lamp that serves as the heat source for the Fuser Roller.
Fuser Roller (316)
A Teflon coated roller supplies the heat for bonding the toner to the paper. The temperature of the
surface is kept constant at approximately 160
°
C (±5
°
C) or (320
°
F) / 155
°
C (±5
°
C) or (311
°
F) / 150
°
C
(±5
°
C) or (302
°
F).
Pressure Roller (322)
This converted PFA tube Silicon Rubber Roller applies pressure to the Fuser Roller, assisting in bonding
the toner to the paper.
Thermistor Assembly (307)
The Thermistor, a heat sensitive resistor, in contact with the Fuser Roller, monitors the surface
temperature. The temperature detected is used to control the ON/OFF switching of the Fuser Lamp. It
also acts as the primary overheat prevention device. A comparator circuit on the SC PC Board acts as a
secondary overheat protection and becomes active at approximately 170
°
C (338
°
F).
Thermostat (310)
A Thermostatic Fuse, part of the power line for the Fuser Lamp, provides an extra overheat protection by
opening when the surrounding temperature reaches approximately 150
°
C (302
°
F). If the primary and
secondary overheat protection does not halt the rise in temperature, the thermostat opens, removing
power from the Fuser Lamp. When the Thermostat opens, it must be replaced.
