The lower second feed roller [A] is driven by the sector gear [B] and the gear
[C]. When the paper feed solenoid [D] is energized the link [E] combined with
the paper feed roller sector stopper [F] is pulled downward and the second
feed roller sector stopper [G] will turn counterclockwise.
When the bearing [H] of the sector gear moves to the top of the lower second
feed roller cam [I], the stopper [G] is released from the sector gear [B] as a
clearance is formed between the pin of the sector gear and the stopper.
Therefore, the bearing of the sector gear will move along the second feed
roller cam face.
When turning the gear [C] counterclockwise, its rotation is not transmitted to
the lower second feed roller due to the one-way clutch bearing press-fit into
the gear [C].
When the bearing [H] of the sector gear moves up from the bottom of the
second feed roller cam [I], the sector gear turns counterclockwise and gear
[C] will turn clockwise. As the rotation of the gear [C] is transmitted to the
lower second feed roller, the lower second feed roller will turn clockwise to
feed the paper to the drum section.
