- While copying the first side - - While lifting the tray -
After the first side copies have been made, the duplex feed motor [A]
changes direction, and the cam clutch gear [B] lifts up the duplex bottom
plate through a series of gears.
While the first side is being copied, the duplex feed motor is rotating
clockwise and the cam clutch gear is rotating counter clockwise (see the
above drawing).
When all copies have been stacked in the duplex tray, the duplex feed motor
rotates counterclockwise, and the cam clutch gear rotates clockwise. The
cam clutch [C] also rotates clockwise because of the spring inside the clutch.
The pin [D] on the clutch lifts up the duplex lift lever [E] through a spring,
raising the duplex bottom plate [F].
When the duplex feed motor rotates clockwise again, the cam clutch rotates
counterclockwise, and the bottom plate lowers.
