5.5 Duplex Unit

5.5.1 Outline

When fixing ends, the paper is moved to the delivery vertical path assembly by the deliv-
ery paper deflecting plate. Then, the paper is turned over in the duplex reversing assembly,
and is sent to the duplex feeding assembly inside the duplex unit.
In the duplex feeding assembly, one of three paper paths is configured by the work of the
paper deflecting plate, and the re-pickup roller performs pickup for the second side.
F02-505-01 and F02-505-02 provide a block diagram of the duplex unit and an outline of
its basic operations, respectively.
