1 Making Overlay Copies

Outline
The figure below shows the paper path used to make overlay copies.
Copy paper that has moved through the fixing assembly is sent to the lower
feeding assembly by the movement of the paper deflecting plate*. In the lower
feeding assembly, the set-back roller puts the incoming sheet in a staggered
stack and waits for the next sheet.
When picked up from this stack (re-pick up), copy paper is discharged by the
movement of the paper deflecting plate 1**.
The solenoid SL5 energises, rotating the deflector in a counter-clockwise di-
rection.
**The paper deflecting plate 1 solenoid (SL5) deenergises so that the paper de-
flecting plate 1 is restrained by the force of the spring.
