Outline

• The surface of the photo conductor is irradiated with a laser light and an electrostatic
latent image is thereby formed.
• The PH unit has a single-piece configuration. A semiconductor laser is provided for each
of four different colors. A single polygon motor is used to make a scan.
• The polygon mirror has seven faces.
• A rotating polygon mirror is irradiated with a laser light emitted from the laser diode on
the laser drive board to let the laser light scan.
