2. BELT DRIVE MECHANISM
When the main motor is on, an idle gear [A] turns the release gear [B]. The
release gear turns the rear transport gear [C], which is mounted on the
transport belt drive shaft [D].
When the transport unit release lever is turned down, the release gear dis-
engages from the idle gear, preventing operation.
The front transport gear [E] on the front end of the transport belt drive shaft
drives the oil pump mechanism.
