CHAPTER 7: PAPER EJECTION SECTION

Mechanism

1. Paper Ejection Mechanism

The printed paper is removed from the print drum by the separator, air blown from the separator and air blown
from two separation fans (one separation fan for model RZ2 series). The removed papers from the print
drum is transferred onto the suction unit. The suction unit contains one large fan which pulls the paper onto
the suction unit and the transfer belts on the suction unit ejects the paper onto paper receiving tray.
The transfer belts are driven by the paper ejection motor, and there is a paper ejection sensor on the suction
unit to confirm whether the paper is correctly received from the print drum and then ejected out on the paper
receiving tray.
The FG sensor disc on the shaft of the paper ejection motor is monitored by the paper ejection FG sensor to
check the motor rotation speed to ensure that the transfer belts are driven at a speed faster than the
circumferential speed of the print drum for smooth paper transfer from the print drum onto the paper receiving
tray.
