1.2.8 FUSING
Overview
After the image is transferred, the copy paper enters the fusing unit. The image is
fused to the copy paper by applying heat and pressure through the use of a hot
roller [A] and pressure roller [B].
The CPU monitors the hot roller temperature through a thermistor [C] that is in
contact with the hot roller surface. A thermostat [D] protects the fusing unit from
overheating.
The hot roller strippers [E] separate the copy paper from the hot roller and direct it
to the exit rollers [F]. The paper feed/exit sensor [G], which is under the fusing unit,
monitors the progress of the copy paper through the fusing unit and detects
misfeeds. The exit rollers [F] drive the copy paper to the paper output tray.
Springs [H] at the front and rear apply the proper fusing pressure between the hot
roller and pressure roller.
The fusing lamp [K] is located in the hot roller.
