2.1 Print Process
2.1.1 Print Process Overview
This is a full-color laser printer using the Xerographic process. This
process forms an image of toner (Yellow, Magenta, Cyan and Black) on
the surface of the drum. The image of one color is then transferred onto
the IBT Belt Assembly (Belt). On the belt, this process is repeated four
times, resulting in a full-color image. The print process is summarized
as follows:
Figure 2-1. Print Process Flowchart
(1)
Charge:
Charges the drum surface.
(2)
Exposure:
Exposes the image with a laser beam.
(3)
Development:
Develops the image with the toner.
(4)
First transfer:
Transfers the toner image on the drum to the
belt.
(5)
Cleaning:
Cleans the drum.
(6)
Repeat:
In the YMCBk mode, steps [1-5] are repeated
for each toner. At the end, the belt has a full-
color image. (The steps are not repeated in
the B/W mode.)
(7)
Second transfer: Transfers the image on the belt onto the
paper.
(8)
Detach:
Removes the electrical charge from the paper.
(9)
Cleaning:
Cleans the belt.
(10) Fusing:
Fixes the toner image to the paper by heat
and pressure.
