Paper Feed

When the /PRNT signal is sent to the system board by the controller
card and the scanner motor is put in the READY state, the system
board issues the print sequence command and printing starts. 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 matches the transfer roll as well as the
leading edge of the image on the photosensitive drum. Subse-
quently, the paper passes through the transfer, fuser, and delivery
units to the face-down or face-up tray.
