The machine picks up the sheet of paper from the manual feeder. The machine uses the manual feeder paper sensor to check the presence/absence of paper in the
manual feeder, and uses the registration roller to move the paper inside the machine.
The cassette presence switch (SR2) detects cassette presence, since the MPT uses the cassette partially for its paper path so that the cassette is necessary for MPT
printing operation.
The MPT paper sensor (SR707) detects paper presence on the MPT.
The MPT pick-up mechanism is to pick up paper on the MPT into the printer one by one. The pad separation is equipped for the multiple-fed prevention.
The following is the operational sequence of the Multi-purpose tray (MPT) pick-up.
1) Upon reception of the print command from the video controller, the DC controller drives the motors in the feeding system.
2) The MPT pick-up solenoid (SL5013) is turned ON and the driving force of the feed motor (M4) is transmitted to the MPT pick-up roller to rotate.
3) The paper is at the position to be picked up by the separation pad, which is pushed up according to the spring force. Then one sheet of paper is picked up by the
pick-up roller rotation and then it is fed into the printer. Thus, the multiple-fed paper is prevented by the separation pad.
