Chapter 5 Pick-Up/Feeding System; Outline Of Operation - Canon NP7160 Service Manual

I. OUTLINE OF OPERATION
The copier uses a center reference feeding method, in which copy paper is moved along the
center of the pick-up/feeding path to ensure stable movement.
The pick-up system consists of the cassette No. 1 holder and the multifeeder. Copy paper
picked up from the cassette or the multifeeder is controlled by the registration roller so that it is
aligned with the leading edge of the image on the photosensitive drum, and is sent through the
transfer, separation, and fixing assemblies and then to the copy tray.
As many as two sensors are used to monitor the movement of the copy paper.
