10.2.6 Paper Feed System

While paper is being stacked in the duplex tray, the paper flatteners [A]

correct curl at the leading edge of the paper.

After all the paper has been stacked in the duplex tray, the jogger fences

square the paper stack and the duplex feed motor rotates counter-clockwise

briefly to prepare to feed the paper from the duplex tray. At this time, the

bottom plate rises and the duplex feed rollers [B] move the flip mylars [C]

back to the right (front view).

The duplex paper feed system consists of three sets of duplex feed rollers

and a separation roller [D]. As the separation roller has a one-way bearing

inside, it rotates freely during paper stacking and locks during paper feeding.

The duplex feed rollers can feed only the top sheet of the stack because the

separation rollers function in the same way as a friction pad does.

After that, the second side copies follow the upper paper tray feed station

paper path.

After the duplex tray runs out the final copy, the paper end feeler [E] drops

through a slot in the duplex bottom plate. The duplex paper end actuator [F],

which is on the same shaft as the duplex paper end feeler, pivots into the

duplex paper end sensor [G]. Then the sensor signals the cpu to stop the

next paper feed cycle.
