The manual feed pickup mechanism picks up sheets of paper in succession from the multi manual feed tray. The sheets of paper stacked in the tray are raised against

the manual feed pickup roller by the inner plate. The manual feed pickup roller is driven by the main motor (M204) via the manual feed pickup solenoid (SL202)

and gears. Only one sheet of paper is picked up by the combination of the manual feed pickup roller and manual feed pickup paper separation pad, and then fed to

the registration roller. These operations are performed for each sheet to be picked. The user must set the size of the paper in the multi manual feed tray using the

operation panel, or the user must register a fixed size in the user mode.

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.

7.4.2 Post-pickup Control after Multi Manual Feed Pickup

iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i

Paper pickup operation ends when paper is pressed against the registration roller. After this, the registration roller starts rotating and the multi manual feed pickup

clutch turns on. This clutch turns off after feeding the paper by the distance equivalent to the paper size - 126.7 mm (*1) -5 mm (*2).

*1 Distance that paper is fed from the multi pickup roller to the point where the registration sensor turns on.

*2 Paper is post-fed to the point which is 5 mm to the training edge.

When the paper size is not specified, paper is post-fed by the distance equivalent to the multi paper feed enabled size (148 mm in longitudinal direction).

Minimum post-feed distance: 148 mm - 126.7 mm -5 mm = 16.3 mm
