10.4 2ND FEED STATION PAPER LIFT MECHANISM AND
PAPER END DETECTION
10.4.1 Paper Lift Mechanism
When the paper tray [A] is closed after the paper is loaded, the release shaft
[B] is pushed by the rear frame [C] and releases the lock arm [D], which is
mounted on the paper tray bottom plate.
Once the lock arm is released, the bottom plate is raised by the pressure
spring [E] and the top sheet pushes up the corner separator [F] and stops at
the correct feed height.
10.4.2 Paper End Detection
When the paper tray runs out paper, the paper end feeler [G] drops through a
slot in the tray bottom plate. The paper end actuator [H], which is on the
same shaft as the paper end feeler, pivots into the paper end sensor [I]. The
paper end sensor sends a HIGH signal to the main board and then the Add
Paper indicator turns on. The Wait indicator keeps turning on and the
machine stops after the copy cycle is finished.
When the paper tray is pulled out, the release arm [J], which is spring loaded,
rotates clockwise and lifts the paper end actuator and the paper end feeler.
This prevents the paper end feeler from being damaged by the paper tray.
When the paper tray is closed, the projection [K] on the paper tray pushes the
release arm to release the paper end actuator and the paper end feeler.
