5. Image Creation Process
[1] Printer Processing • The intensity of the laser light is controlled based on the image
signal transmitted from the host computer.
[2] PC Drum • The image of the original projected onto the surface of the PC
Drum is changed to a corresponding electrostatic latent image.
[3] PC Drum Charging • Apply DC (-) charge to the photo conductor.
[4] LD Exposure • The surface of the PC Drum is irradiated with laser light, and an
electrostatic latent image is thereby formed.
[5] Developing • 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.
[6] 1st Image Transfer • 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.
[7] 2nd Image Transfer • 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.
[8] Paper Separation • The paper, which has undergone the 2nd image transfer process,
is neutralized so that it can be properly separated from the Trans-
fer Belt.
[9] Transfer Belt Cleaning • The residual toner left on the surface of the Transfer Belt is
scraped off.
[10] PC Drum Cleaning • The residual toner left on the surface of the PC Drum is scraped
off.
