When the paper feed station is selected and the start key is pressed, the feed
clutch [A], separation roller solenoid [B], and the pick-up solenoid [C] turn on
at once.
When the feed clutch [A] activates to rotate the feed roller [D], the feed roller
and the pick-up roller [E] turn together because they are linked by the idle
gear [F].
When the separation roller solenoid [B] turns on, the separation roller [G]
contacts the feed roller [D] then rotates together with the feed roller in spite of
the separation roller's drive in the opposite direction due to the torque limiter
function in the separation roller [G].
When the pick-up solenoid [C] activates, the pick-up roller [E] lowers to make
contact with the top sheet of the paper stack and send it to the feed and
separation rollers.
When the paper feed sensor [H] detects the leading edge of the paper [I], the
pick-up solenoid de-energizes to lift the pick-up roller and the paper feed
clutch de-energizes at a certain time to wait until it is ready to feed to the
registration roller.
