Paper Feed Tray Bottom Plate Lift Mechanism
When you slide the paper feed tray into the unit, the bottom plate arms [1] slide along the sloping guide of the main
frame, and then the bottom plate is pushed upward by the springs.
As a result, the lifted bottom plate presses the sheet on the top of the stack up against the paper feed roller.
Side-to side Registration Adjustment in the Machine Paper Feed Tray
To adjust side-to-side registration, loosen the two screws on the underside of the tray and move the rack and pinion
mechanism of the side guides from side to side.
Bypass Tray Paper Feed Operation
When the paper feed signal is received by the Bypass Feed Tray, the Bypass Bottom plate is lifted up, and then the
Bypass Clutch is turned on to rotate the Bypass Feed Roller.
The friction pad ensures that only the top sheet is fed. After the paper is fed out, the Duplex Exit Clutch is turned on to
feed the paper along the same path as is used for feeding paper from the Paper Feed Tray. When the paper fed into the
machine activates the Registration Sensor, the Bypass Clutch is turned off. When the toner pattern on the transfer belt is
at the correct position, the Registration Clutch is turned on to feed the paper to the Image Transfer Unit.
