The paper in the tray of the manual feed pickup unit is forced against the manual feed pickup roller by the work of
the pickup guide plate; the manual feed pickup roller and the separation pad serve to make sure that only a single
sheet of paper is separated and moved into the machine:
(1) the pickup guide plate is locked in place at all times, and does not require drive for pickup operation.
(2) multi-pickup roller is driven by the main motor (M2) through the manual feed pickup clutch (CL1).
