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.
