• The intensity of the laser light is controlled based on the image
signal transmitted from the host computer.
• 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 photo conductor.
• The surface of the PC drum is irradiated with laser light, and an
electrostatic latent image is thereby formed.
• The toner, agitated and negatively charged in the toner chamber,
is attracted onto the electrostatic latent image formed on the sur-
face 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 media,
thereby allowing the visible, developed image on the surface of
the transfer belt to be transferred onto the media.
• The media, which has undergone the 2nd image transfer process,
is neutralized so that it can be properly separated from the trans-
fer belt.
• The residual toner left on the surface of the transfer belt is
scraped off.
• The residual toner left on the surface of the PC drum is scraped
off.
