This machine uses four PCUs, four development units, and four laser beams for
color printing. Each PCU consists of a drum, charge roller, cleaning brush, and
blade. From the left, the PCU stations are black, yellow, cyan, and magenta.
A transfer belt feeds paper past the PCUs, and the toner image on each drum is
transferred to the paper.
The paper path is inclined about 38 degrees to make the machine as compact as
possible.
