Printing method
Introduction
The print image is created through an electrophotographic printing process with LED
print heads and two-component developers.
With a full color printing system, the colors are generated using the subtractive color
mixing technique, using the color separations cyan, magenta and yellow:
To reduce the coverage and achieve a greater depth with dark colors, black is also used
as the fourth color.
Printing Process

Description Level
The rastered controller pages are written to the photoconductor belt
with the LED print head.
■
During bilevel printing, each dot can be assigned either 100% color
or 100% white (= LED in LED print head on or off).
■
During multilevel printing, the light intensity of each LED can range
between 16 brightness levels. This dot modulation allows continuous
runs.

The developer station inks the image pattern. 2
The inked image pattern is transmitted from the photoconductor belt
to the transfer belt. 3
