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.
