An independent paper feed motor [A] drives the rollers in each tray. It also drives
grip rollers [B], which pull the paper out of the tray. The mechanism is identical for
each tray.
A vertical transport sensor [C] at each feed station detects paper jams.
The paper feed motors on the trays drive the vertical transport rollers, which are
opposite each feed station (not shown here).
The lower relay motor [D] drives the lower relay roller [E], halfway between trays 1
and 2. The relay motor is added here due to the length of the paper path.
The upper relay roller [F] feeds each sheet to the registration roller. The by-pass
feed motor (not shown here) drives the upper relay roller [F].
The relay sensor [G], at the top of the vertical transport path, triggers the start of
image exposure on the OPC drum, and detects jams in the paper path.
The transport guide plate [H] swings against the side of the machine and locks in
place.
