• The intensity of the laser light is controlled based on the image signal transmitted to this board.
• The surface of the PC drum is irradiated with laser light, and an electrostatic latent image is thereby
formed.
• The image of the original projected onto the surface of the PC drum is changed to a corresponding
electrostatic latent image.
• Apply DC (-) charge to the drum.
• The toner, agitated and negatively charged in the toner chamber, is attracted onto the electrostatic
latent image formed on the surface of the PC drum. It is thereby changed to a visible, developed image.
• A DC positive voltage is applied to the backside of the transfer belt, thereby allowing the visible,
developed image on the surface of each of the PC drums (Y, M, C and K) to be transferred onto the
transfer belt.
• A DC positive voltage is applied to the backside of the paper, thereby allowing the visible, developed
image on the surface of the transfer belt to be transferred onto the paper.
• The paper, which has undergone the 2nd image transfer process, is neutralized so that it can be
properly separated from the transfer belt.
• The residual toner left on the surface of the transfer belt is scraped off.
