9.2 Operation
9.2.1 Operation of bypass pickup roller
When the paper is set on the bypass tray, the bypass feed sensor detects the presence of the paper.
Then the bypass pickup solenoid is turned ON and the pickup arm falls by its own weight. At this time,
when the bypass feed clutch is turned ON, the drive from the equipment is transmitted to the pickup
roller through the coupling and timing belt. Then the paper is picked up.
The paper picked up is transported to the transport path on the equipment side by the feed roller and
transport roller.
When there is no paper remaining on the bypass tray, the bypass pickup solenoid is turned OFF and
the pickup roller returns by the spring force.
The separation roller works not to transport paper more than one sheet at a time.
9.2.2 Operation of drawer pickup roller
Fig. 9-202
When the drawer is inserted, the pickup roller and roller holder fall by the spring force. Then the drawer
tray lifts up and paper feeding is enabled.
When the drawer feed clutch is turned ON, the drive from the equipment is transmitted. Then the feed
roller and pickup roller rotate to transport the paper from the drawer.
The separation roller under the feed roller prevents multiple transporting of paper.
