Phaser 6180 Printer Operational Overview
The Phaser 6180 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 
xerographic process (dashed lines) and the paper flow (solid lines) into and 
out of the Phaser 6180 Printer.
