Printing
The printing segment is the hardware, often referred to as the print engine.
To become familiar with the basic functions of a print engine we demonstrate
with a color print engine.
1
Laser Unit: The laser unit & is controlled
by the contents of the Frame Buffer (for
each color). For each dot color of the
Frame Buffer bitmap that is turned on, the
laser is switched on and “writes” an
electrical dot onto the OPC in the print
unit.
"#
An electrical dot is an isolated area
on the surface of the OPC. The OPC is initially charged. When the
laser beam strikes the surface, that area is electrically neutralized.
2
Toner:
Each toner cartridge ' transfers its toner to the neutral areas on
the print unit by means of electrostatic attraction (the toner carries a
negative charge).
3
Print Unit with OPC: The
laser unit “writes” the dots from
one side to the other, while the
rotation of the OPC (Organic
Photo Conductive) in the print
unit
( is responsible for the
vertical movement (lines of
dots).
