The copier exit roller gear [A] drives the transport rollers [B] through the
timing belt [C].
All the rollers in the duplex tray are driven by the duplex feed motor [D]. The
drive of the duplex feed motor is transmitted to the duplex feed rollers [E] and
the duplex entrance rollers [F] through a series of gears. All the gears have
diagonal teeth to reduce driving noise.
The duplex feed motor also drives the duplex bottom plate up and down.
