CHAPTER 2 BASIC OPERATION
E. Turning Over an Original/Delivery
1. Outline
An original is delivered by the reversal delivery roller and the reversal delivery link roller using
the drive of the reversal delivery motor (M3).
The ADF moves an original by the reversal delivery roller in feeding direction, switches the
feeding path, and rotates the reversal delivery motor counterclockwise to start delivery. In other
words, originals are delivered to the delivery tray face down, starting with the first page.
The feeding path is switched by opening and closing two flappers. The reversal delivery
registration sensor and the delivery sensor operate in conjunction with the two levers located in the
feeding path, and turn on or off according to the direction of rotation of the reversal delivery motor.
