CHAPTER 5 PICK-UP/FEEDING SYSTEM

II. PICK-UP OPERATION (COPIER)

A. Outline

When the pick-up clutch (CL2 or CL3) turns on while the main motor (M1) is rotating, the pick-up roller rotates to move paper as far as the registration roller.

The copy paper is controlled so that its leading edge and the leading edge of the image on the photosensitive drum match; then, it is moved through the transfer assembly, feeding assembly, fixing assembly, and delivery assembly to reach the copy tray.

As many as three photointerrupters (PS6, PS7, PS8) are provided along the paper path, turning on the Jam indicator on the control panel when jams are identified in terms of whether paper has reached or has moved past the respective sensors within a specific period of time.

The presence/absence of paper inside the cassette or the multifeeder is monitored by separate photointerpreters (PS4, PS5); when the absence of paper is identified, the Paper indicator is flashed on the control panel.
