CHAPTER 2 OPERATION OVERVIEW

12.5 Folding and Delivery System

12.5.1 Overview

The folding mechanism is composed of a guide plate, folding rollers, paper retaining plate
and paper positioning plate.
The guide plate covers the folding rollers while the paper is being collected and prevents
the paper from coming into contact with the rollers. The guide plate is lowered during the
folding operation, to allow folding to take place.
The folding rollers are driven by the folding motor (M42). The folding motor clock sensor
(PI67) monitors the running of the motor. The paper folding home position sensor (PI58) is
used to detect the position of the paper folding rollers. The paper retaining plate is driven by
the paper retaining plate motor (M48) which is monitored by the paper retaining plate motor
clock sensor (PI45). The paper retaining plate home position sensor (PI55) and paper retain-
ing plate front edge position sensor (PI56) detect the position of the paper retaining plate.
After being folded in two by the folding rollers, the paper is stack delivered by the delivery
rollers. The delivery rollers are driven by the folding motor. A delivery sensor (PI52) detects
delivery of the paper into the delivery area. . The vertical path jam clear sensor (PI57) de-
tects whether any paper has been left behind after a jam has been cleared.
