1. Fusing Drive
Release Gear
The fusing drive gear turns the release gear
which drives the hot roller gear.
Hot Roller Gear
Rotation passes from the hot roller gear
through two idle gears to the exit rollers.
The pressure roller is driven by the friction
between the two fusing rollers.
The release gear spring allows the release
gear to move in and out. This prevents the
gears from being damaged if they should not
engage correctly when the fusing unit is
installed. Also, by pulling on the fusing knob,
the operator can disengage the release gear
Exit Roller Gear
and the fusing drive gear so that the fusing
Fusing Drive Gear
rollers can be turned easily for removing
