Figure 2 Line Screen Rotation
In cluster mode, the ROS laser beam is modulated to create fewer but larger pixels on the pho-
toreceptor drum. The size of these pixels by can
be changed by c
hanging the total amount of
energy which the lasers transmit to the photoreceptor drum. The pixels are arranged in groups
or clusters with one pixel per color, with each pixel being effectively rotated. The arrangement
of pixels is shown in Figure 3.
