b. Inner Plate Lift Operation
During standby, the inner plate is at the down position with it held by the cams provided at the front and back of the manual feed pickup roller shaft. Rotation of
the pickup roller rotates the interlocked cams to lift the inner plate, raising the sheets of paper (loaded in the manual feed tray) against the manual feed pickup roller.
On the opposite side of the pickup roller is mounted a separation pad that separates only one sheet of paper from others and feeds it to the next section.
c. Manual feed Tray Pickup Drive Mechanism
pickup solenoid drive signal (MFPD) sent from the DC controller PCB. Rotation of the main motor drives the pickup drive power transfer gear. The DC controller
PCB issues a manual feed pickup solenoid drive signal (MFPD). When the solenoid turns on, the stopper operates to rotate the pickup roller once. Next, the stopper
operates again to stop rotation of the pickup roller.
