6.1.2. Receive Mechanism
Paper Feed Operation of ASF (Auto Sheet Feeder)
One sheet of Recording Paper at the time is fed with the rotation of the Motor (501) and the feed roller
which is controlled by the Clutch Assembly (424, 425, 426, 427 and 460) and the Solenoid (431).
The Pressure Plate (404) moves up, the top sheet of paper is fed in with the Pick Roller (436).
The Paper Separation Pad (417) ensures that the ASF Roller (435) feeds only one sheet of paper at
the time.
The
Pressure Plate (404) moves down and the R and L Paper Stoppers (413, 414) rotate clockwise as
shown in the illustration above, stopping the remaining papers in the Paper Tray, then the Paper
Separation Pad (417) moves down completing the paper feed operation cycle.
The Paper Separation Pad (417) and the Pressure Plate (404) move down to reduce drag on the
recording paper during the paper feed operation and to minimize paper dust from occurring.
The paper is transported by the
Feed Roller (439) to the Drum Unit. The actual printing process starts at
a specified time after the Timing Actuator (455) (Registration Sensor) is activated and stops at a
specified period of time after the trailing edge clears the Timing Actuator (455).
