10.2.5 Paper Feed from the Duplex Tray

While the first side is being copied, the duplex feed motor [A] is rotating

clockwise and the cam clutch gear [B] is rotating counter-clockwise (see the

above drawing). Then all copies are stacked in the duplex tray unit.

After the first side copies have been made, the duplex feed motor [A]

changes direction, and the cam clutch gear [B] rotates clockwise. The cam

clutch [C] also rotates clockwise because of spring inside the clutch. The pin

[D] on the clutch lifts up the duplex lever [E] through a spring, raising the

duplex bottom plate [F].

Then the stacked copies are fed by the duplex feed rollers to begin reverse

side copying.
