The Phaser 6125/6130 Color Laser Printer is a full-color laser printer that
uses Raster Output Scanner (ROS) lasers with an electrophotographic four-
color CMYK process. The tandem system consists of four color drums (C, M,
Y, and K) which creates the toner image.
The following block diagram provides the sequence of events for the
xerographic process (dashed lines) and the paper flow (solid lines) into and
out of the printer.
