the transfer drum. These steps are taken for each color. The
paper is rotated on the transfer drum until the color transfer
process is completed.
The paper is then separated from the transfer drum and
delivered to the fixing unit. The surface of the photosensitive
drum is cleaned with the cleaner blade for removal of remaining
toner, and the drum potential is kept uniform by the primary
charging roller in preparation for forming a new latent image.
The transfer drum surface is cleaned with the cleaning brush for
removal of remaining toner and the discharge roller removes the
surface charge.
This printer is also equipped with toner cartridge installation
detection, toner-low detection, toner stirring, and
photosensitive drum life detection functions.
Note:
The cleaning brush is activated after 100 prints.

Pick-up/Feed system—When a print job is sent to the printer a
sheet of paper is picked up by either the cassette or manual
feeding pick-up roller, fed by the feed rollers. Any skew in the
paper is corrected by the registration roller, and then the paper
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, fixing, and delivery units
to the face-down or face-up tray.
