Front Feeding Mechanism
The front feeding mechanism is composed of the Pick-up mechanism and the
intermediate feeding mechanism.
 Pick-up mechanism
This mechanism picks up paper from the Cassette Assy and feeds it up to the
intermediate feeding mechanism. The retard separation method is used for
paper separation.
The ASF Motor drives the pick-up mechanism. The pickup roller and
separation roller uses a oneway clutch to always rotate in a set direction (paper
feed direction) only. When the ASF Motor rotates the opposite direction of
paper feeding, the drive force is cut off by the One Way Clutch, so neither the
Pick-up Roller nor Separation Roller rotates.
