An independent paper feed motor [A] drives the rollers in each tray. The motor also
drives grip rollers [B], which pull the paper out of the tray. This mechanism is
identical for each tray.
A vertical transport sensor [C] at each feed station detects paper jams.
The paper feed motors of each tray drive the vertical transport rollers, opposite to
each feed station (not shown).
The lower relay motor [D] drives the lower relay roller [E], halfway between trays 1
and 2. The lower relay roller is added here because the paper path is very long.
The upper relay roller [F] feeds each sheet to the registration roller. The by-pass
feed motor (not shown) 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.
