Drum charge The charge rollers [B], one for each color development, apply
a negative charge to the OPC drums [C]. There are four
drums, one for each toner color.
"
Laser optics The polygon mirror [A] and other mirrors reflect the laser
beams. There are four beams, one for each toner color.
# Laser exposure
and toner
transfer
The laser beams create (write) the image to be developed
(latent image) on the OPC drums. Then, toner is transferred
to areas that were exposed to the laser beam.
$ Belt transfer A transfer belt [D] rotates past the drums, and the toner on the
drum is transferred to this belt in the order Y, M, C, K. All four
colors transfer to the belt in one belt rotation.
% Paper feed After all colors have transferred to the belt, a sheet of paper is
fed up from below the transfer belt to the transfer roller [I].
&
Paper transfer The transfer applies a positive bias to the “back” of the paper
which transfers the toner to the paper.
' Fusing The paper advances to the fusing unit [J], where heat and
pressure permanently bond the toner to the paper.
(
Paper exit
The paper is then fed out of the machine.
