8.3 Operation
8.3.1 Operation of bypass pickup roller
Fig. 8-3
When the bypass pickup solenoid (SOL3) is turned ON, the plunger is pulled and the lever is revolved
and brought down. The pickup arm, which is linked with the lever, is also brought with the lever by its
own weight. When the bypass pickup solenoid (SOL3) is turned OFF, the pickup arm is brought up by
the spring force.
The driving force transmitted through the bypass feed clutch (CLT4) is also transmitted to the bypass
feed roller through the shaft and then to the bypass pickup roller through the timing belt. The roller is
rotated by this driving force.
8.3.2 Operation of drawer pickup roller
Fig. 8-4
When the drawer is inserted, the protrusion at the rear side of the drawer pushes the lever to the
direction of A. Then the pickup roller and roller holder are lowered by the spring force.
