The Phaser 6280 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 print cartridges (C,
M, Y, and K) which creates the toner image.
The following block diagram provides the sequence of events for the
