Paper transport mechanism

A. Paper path switching mechanism
• The paper fed from the main unit moves through either one of the two different paper
paths.
• A solenoid is used to select the paper path.
For switchback sequence during 2-sided printing: Solenoid energized
For transport onto the Finisher: Solenoid deenergized
Turnover Empty Sensor (PC6-FN)
B. Finisher paper transport mechanism
• A motor is employed to transport paper onto the Finisher.
• The Paper Sensor functions to detect a sheet of paper present in the Horizontal Trans-
port Unit.
