2.2.6 Mechanical Drive for Registration

The Main Motor provides mechanical drive for the Registration Roll. The
Main Drive Assembly transmits drive to the Registration Clutch. At a
specific time in the print cycle the MCU switches on the Registration
Clutch. The Registration Clutch transmits drive to the Registration Roll,
which rotates and drives the sheet of paper into the Drum/BTR area.

2.2.7 Mechanical Drive for the Drum and BTR

The Main Motor provides mechanical drive for the Drum and BTR. The
Main Drive Assembly transmits drive to the Drum. A shutter covers and
protects the Drum surface. When the Left Cover is closed, a mechanical
link opens the Shutter. When the Left Cover is open, the link closes the
Shutter. A gear attached to the end of the Drum transmits drive to the
BTR. Since the BTR is attached to the Left Cover Assembly, the BTR is
driven only when the Left Cover is closed.
