Pickup From The Multifeeder Tray - Canon iR1600 Service Manual

2.2.2 Pickup from the Multifeeder Tray

a. Movement of the Holding Plate
While in standby, the holding plate is at the bottom supported by the cams mounted to the
front and rear of the manual feed pickup roller shaft.
When the pickup roller rotates, the cams start to rotate in response, causing the holding
plate to move up so that the paper placed in the multifeeder comes into contact with the
pickup roller.
The separation pad is mounted opposite the pickup roller, serving to separate one sheet of
paper and sending it to the inside of the machine.
b. Multifeeder Tray Pickup Drive Mechanism
The manual feed pickup roller rotates by the drive of the main motor reaching the gear of
the manual feed tray pickup drive assembly. The timing at which paper is picked up is con-
troller by the manual feed pickup solenoid drive signal (MFPD) from the DC controller
PCB.
As soon as the main motor starts to rotate, its drive is transmitted to the pickup drive
transmission gear.
When the DC controller PCB generates the manual feed pickup solenoid drive signal
(MFPD) and the solenoid goes ON as a result, the stopper will be released so that the pickup
roller stops to rotate.
