When the leading edge of the original reaches the entrance sensor, the pick-up
roller motor switches on again, to lift the pick-up roller away from the original stack.

Home position is detected by the pick-up roller HP sensor.

When the trailing edge of the original passes the entrance sensor, and there are
still some originals on the tray, the pick-up roller is again dropped onto the stack of
originals.

Details of the mechanism are as follows:
