    Basic Operation 2.2 BASIC OPERATION 2.2.1 PAPER SEPARATION AND FEED The paper tray holds 500 sheets of paper. The paper feed unit uses a friction pad system. The gear [A] is driven by the transport/fusing motor in the mainframe. The relay clutch [B] and paper feed clutch [C] control drive from the mainframe. When the optional tray is selected as the feed tray, the relay clutch and paper feed clutch transmit drive power to the relay roller and paper feed roller.

  • Page 299: Paper Lift

    Basic Operation 2.2.2 PAPER LIFT The bottom plate is always pressed up by the spring in the tray. Therefore, you must press down the bottom plate when you insert the tray in the machine. The bottom tray lock levers [A] hold the tabs [B] under the bottom plate after the bottom plate is pressed down.

  • Page 300: Paper End Detection

    Basic Operation 2.2.3 PAPER END DETECTION There is a paper end sensor [A] in the tray. The feeler [B] drops into the cutout [C] in the bottom plate and the actuator interrupts the paper end sensor. This sensor also detects whether the tray is set.
