2-28 Phaser 5500 Printer Service Manual
Trays 2 and 3 are functionally equivalent in terms of the feeder mechanism that moves
paper from the tray into the paper path. The Feeder’s Feed/Lift Motor drives the Feed
and Nudger Rollers to pick paper from the tray, and also lifts the tray’s Bottom Plate
to maintain paper contact with the Nudger Roller.
The Feeder’s Level Sensor uses an actuator to determine whether paper in the tray is
lifted to the feeding position. As the level of paper drops, the flag of the actuator
enters the Level Sensor’s sensing area, triggering the Feed/Lift Motor to raise the
Bottom Plate. The Feeder’s Feed/Lift Motor raises the Bottom Plate by rotating the
Lift-up Shaft through the Gear (13T/60T) and Sector Gear (60T).
