Staple Finisher Operation - Lexmark CX825 Service Manual

During the feed, the elevator plate raises the paper until the paper comes into contact with the pick roller. The
sensor (2200‑sheet tray pick roller index) detects if the pick roller is sufficiently engaged with the paper. The
motor (2200‑sheet tray lift) controls the movement of the elevator plate. As the amount of paper lessens, the
elevator plate also continues to move up. When the tray is almost empty, the actuator triggers the sensor
(2200‑sheet tray media low).
After the pick roller is in position, it feeds the topmost paper to the transport rollers on the upper tray. Separator
pads opposite the pick roller ensure that only one sheet is fed a time. The motor (2200‑sheet tray pick) drives
the pick roller.
