Mechanical Drive for the Fuser
The Main Motor provides mechanical drive for the Fuser Assembly. The Main Drive
Assembly transmits drive to the Fuser Drive Assembly and on to the Fuser Hot Roll Gear.
A gear at the end of the Hot Roll drives the Pressure Roll. The Heat and Pressure Rolls
rotates continuously while the Main Motor is on and the Left Front Cover is closed. Part of
the same mechanical link that opens and closes the Drum Shutter when the Left Cover is
closed, pushes the Fuser Drive Gear against the Fuser Hot Roll intermediate gear, which
transmits drive to the Fuser Hot Roll.
