FUSING UNIT

6.9.2 DRIVE

The main motor drives the fusing clutch ( 6.1.3). The fusing clutch transfers
rotational drive when it is energized (activated).

6.9.3 PRESSURE UNIT

The fusing unit has a pressure roller. The pressure roller presses the pressure-
roller sheet on to the hot roller. As the hot roller turns, the pressure-roller sheet
turns. The paper passes between the pressure-roller sheet and the hot roller.
There are two tension arms, one is located on the right side and the other is
located on the left side of the fusing unit. These tension arms press the pressure
roller to the hot roller. The tension arms are attached to the frame with two tension
bolts and two springs. You can release the pressure created by the tension arms
by pulling up the two tension levers. Releasing the pressure may be necessary to
remove jammed paper from the fusing unit.

6.9.4 FUSING PROCESS

The hot roller and the pressure roller are approximately 150°C (302°F) during the
fusing process. The pressure between these two rollers is approximately 300 N
(Newtons)
