VI. PICK-UP/FEEDING SYSTEM

A. Outline

The GP215/GP200 uses center reference, in which copy paper moves along the center of the pick-

up/feeding assembly. The pick-up system consists of two cassettes (upper, lower) and the multifeeder.

Copy paper from any of the cassettes or the multifeeder is controlled by the registration roller so that

its leading edge matches the leading edge of the image on the photosensitive drum; the paper is then sent

to the copy tray.

As many as nine sensors are used to monitor the movement of copy paper. (Seven sensors are used

to detect jams.)

Figure 3-601 shows the arrangement of sensors (electrical input parts), and Figure 3-602 shows the

arrangement of motors as well as clutches and solenoids (electrical output parts). (The figures do not

cover the cassette drive system.)
