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.
