Operating Principles

2.2.4.1 ASF (Auto Sheet Feeder) Mechanism

Torque from the PF roller is transmitted to the pick up roller in the ASF mechanism via the planetary gear
by the PF motor drive disengage mechanism which switches the torque based on the detected position of
the CR unit. The pick up roller shaft has 2 arms on the right and left ends. The arms push down the paper
support to make the paper surface contact with the pick up roller. The one way clutch rotates the puck up
roller in the specified direction to load paper. The paper loaded is then fed by the paper feed mechanism
and the gear transmission from the planetary gear is disengaged.
