3. OPERATIONS AND TIMING
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.)
