VI.PICK-UP/FEED SYSTEM
A. Outline
This printer utilizes two paper pick-up sources, the cassette and multi-purpose tray, and two
delivery slots, the face-up tray and face-down tray.
Print paper, loaded in either the universal paper feed tray or manual the feed tray, is picked
up by the pick-up roller. Then the paper is delivered to the photosensitive drum and transfer
charging roller, the fixing film unit and pressure roller, the face-up delivery roller, and the face-
down deliver roller, and finally delivered to the face-down tray. For face-up delivery, the print
paper is delivered to the face-up tray without passing though the face-down delivery roller.
These rollers mentioned above are driven by the main motor (M001). Note that the pick-up
roller makes one rotation only when the pick-up solenoid (SL001) is turned ON.
Paper presence in both the cassette and multi-purpose tray is detected by the paper out
detection sensor (PS201). The paper path has two photointerrupters, the top of page sensor
(PS402) and delivery paper sensor (PS401) to detect print paper reaching and passing.
If the print paper does not reach or pass through each sensor, the CPU on the engine con-
troller judges it a jam and notifies it to the interface controller.
