12.2 FUSING DRIVE MECHANISM

The fusing drive gear [A] turns the release gear [B] which drives the hot roller gear [C].
Rotation passes from the hot roller gear through two idle gears [D] to the exit roller drive gear
[E]. The pressure roller is driven by the friction between the two fusing rollers.
The release gear spring [F] allows the release gear to move in and out. This prevents the
gears from being damaged if they are not aligned correctly when the fusing unit is set. Also,
by pulling on the fusing knob, the operator can disengage the release gear and the fusing
drive gear to turn the fusing rollers and remove misfeeds.
