5045-001 Pickup / Feed System Theory When the /PRNT signal is sent to the DC controller by the video controller and the scanner motor is put in the READY state, the DC controller issues the print sequence command to the mechanical controller, which then starts printing. After a sheet of paper is picked up by the cassette pickup roller or the manual feeding pickup roller, it is fed by the feed rollers. Any skew of the paper is corrected by the registration roller and it stops at the leading edge detection position. The temporarily stopped paper is fed so that its leading edge will match the gripper on the transfer drum as well as the leading edge of the image on the photosensitive drum. Subsequently, the paper passes through the transfer, separation, fuser, and delivery units to the face-down or face-up tray. 2-34
