5.5.3 PICK-UP AND FEED
When a paper feed station is not selected, its separation roller solenoid [A] is de-
activated and the separation roller [B] can turn freely.
When the paper feed station is selected and the Start key is pressed, the feed
clutch [C], separation roller solenoid [A], and pick-up solenoid [D] turn on.
When the feed clutch [C] actuates, it drives the feed roller [E], and turns the pick-up
roller [F] 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, unless more than one sheet
of paper is fed. The three trays of the LCT unit use the standard FRR mechanism.

(FRR)
When the pick-up solenoid [D] actuates, the pick-up roller [F] lowers until it contacts
the top sheet of the paper stack and then sends it to the paper feed and separation
roller.
When the paper feed sensor [H] detects the leading edge of the paper, the pick-up
solenoid de-actuates and lifts the pick-up roller [F], and the grip roller clutch [I]
actuates and feeds the paper out of the tray.
