2.2.4.1 ASF (Auto Sheet Feeder) Mechanism

When the printer is not printing, the motor drive disengage mechanism switches the torque sent from

the PF motor to the LD rollers in the mechanism via the planetary gear based on the detected position

of the unit. The roller shaft has 2 cams on the right and left ends. They push down the paper

support to make the paper surface come in contact with the rollers. The one way clutch rotates the

roller in the specified direction to load paper. Once the paper is loaded, the torque from the planetary gear

is disengaged and the paper is then transported by the paper feed mechanism.
