4.1 11 x 17 PAPER SIZE
1. When the leading edge of the paper [A]
has passed through the fusing unit, the
junction gate solenoid energizes and the
junction gate [B] is opened. The paper is
guided into the inverter unit [C]. The on
timing of the junction gate solenoid is
controlled by the registration sensor.
2. The paper is fed to the duplex tray [D] by
the inverter unit transport roller [E], and
to the duplex feed roller [F] by the left
and central transport rollers ([G], [H]) in
the duplex tray. When the trailing edge of
the paper has passed through the duplex
entrance sensor [I], the speed of the
paper movement will be doubled.
3. The paper is inverted by the duplex feed
roller [F]. The duplex feed motor turns off
shortly after the trailing edge of the paper
passes through the duplex turn sensor
[J].
