Paper Feed Unit
1. Description
The paper loaded on the feed tray is raised by the
elevator motor. When the paper is in the required
position, a jet of air from a fan in front of the paper
causes several sheets of paper to rise up. The suction
unit pulls up the top sheet only, and then the feed motor
drives the suction belt to transfer the paper.
When the paper from the AF-100 reaches the PPS1 in
the DC-545, the paper is transferred to the paper path by
the press roller and the feed stepping motor.
A separator mechanism is used to prevent two or more
sheets from being transferred at one time.

2. Operation
1) Processing starts (processing does not start if there is no paper).
The fan (blower) and the fan (suction) start running.
2) The feed tray starts rising.
3) The feed tray stops when the paper level sensor turns on (light is not transmitted).
4) The shutter solenoid operates and the shutter opens and the paper is sucked onto the suction unit.
5) The feed motor starts and the suction belt begins turning to transfer the paper.
6) The feed motor stops when the paper reaches PPS1 (light is not transmitted).
If paper does not reach PPS1 within about 2.5 seconds, the elevator falls repeating operations 3) to 5) until
the paper level sensor turns off (light is transmitted). If the operation is repeated three times before the paper
reaches PPS1, a J2: FEED JAM error occurs and the machine stops.
