Paper Exit Roller Drive Coupling Mechanism
When the duplex unit is mounted, the tip of the duplex unit lever
raises the idle lever. This disconnects the printer drive (fusing roller)
from the paper exit roller and connects the switchback motor drive.
Switchback Motor Control
The switchback motor is a two-phase stepping motor.
Transport and Duplex Paper Take-Up Mechanism
Transport and Duplex Paper Take-Up Operation
The transport and duplex paper take-up operations are performed
by two pairs of duplex unit transport rollers/rolls and the manual feed
paper take-up roll of the printer. The drive for these operations
comes from the duplex unit transport motor and manual feed paper
take-up clutch.
