PAPER FEED

Pick-up and Feed
If a paper feed station is not selected, its separation roller solenoid [A] de-activates
and the separation roller [B] can turn freely in the opposite direction to paper feed.
When the paper feed station is selected and the start key is pressed, the feed
clutch [C], separation roller solenoid [A], and the pick-up solenoid [D] all turn on.
When the feed clutch [C] activates to transfer drive to the feed roller [E], the pick-up
roller [F] also turns because it is linked to the feed roller by an idle gear [G].
When the separation roller solenoid [A] turns on, the separation roller [B] contacts
the paper feed roller [E] and turns with the feed roller in spite of the torque limiter in
the separation roller, which forces it in the opposite direction.
When the pick-up solenoid [D] activates, the pick-up roller [F] lowers to make
contact with the top sheet of the paper stack and send it to the paper feed and
separation rollers.
When the paper feed sensor [H] detects the leading edge of the paper, the pick-up
solenoid de-energizes to lift the pick-up roller [F], and the vertical relay clutch [I]
energizes to feed the paper to the vertical paper feed section.
