FUSING AND PAPER EXIT
Sensor Assembly Photo Exit and Actuator-Exit:
Detect when paper passes the position just after
the Fuser.
Roll Pressure: A roll with spon
g
e rubber attached around a
metal shaft. The Roll Pressure is pressed up by
the sprin
g
s and applies pressure to the paper
passin
g
between itself and the Roll Fuser.
Fuser Unit:
Roll Fuser
:
A hollow, surface-coated metal tube that is
heated by the Heater lamp held inside the roller.
The toner on the paper is melted and bonded to
the paper by means of heat and pressure
applied by the rollers.
Heater Lamp
:
A
g
lass tube with a heat
g
eneratin
g
coil sealed
in it. The Heater Lamp is located inside the Roll
Fuser and heats the Roll Fuser.
Sensor Assembly Temperature:
A resistor (thermistor) whose resistance varies
sharply in a known manner with the
temperature. This sensor is held in contact with
the surface of the Roll Fuser and monitors the
temperature. The si
g
nal from this sensor is used
to maintain the temperature of the surface of the
Roll Fuser within the specified ran
g
e by
switchin
g
on and off the AC power to the Heater
Lamp. The si
g
nal is also used for the first-sta
g
e
overheat protection.
