Operation of drawer pickup roller
Lever
When the drawer is inserted, the protrusion at the rear side of the drawer pushes the lever to the direc-
tion of A. Then the pickup roller and roller holder are lowered by the spring force.
9.3.3
Paper separation
This model is equipped with a separation roller which works to prevent multiple paper feeding. The sep-
aration roller unit consists of the feed roller, separation roller, torque limiter, etc., as shown at right.
The feed roller is rotated by the feed clutch in the direction of the white arrow at the same timing as the
pickup roller rotation.
The figure at right shows how duplicate feeding is prevented: Since the friction between two sheets is
small, the lower sheet is not transported any further while the upper sheet is transported by the feed
roller in the direction of the black arrow.
