2-2 Phaser 6300/6350 Color Laser Printer Service Manual
Phaser 6300/6350 Operational Overview
The Phaser 6300/6350 Color Laser Printer is a full-color laser printer that utilizes 
electrophotographic recording principals to place a full color image onto the print 
media. The system, as it appears in the following illustration, contains a drum and 
developing unit for each color [yellow, magenta, cyan and black (YMCK)], and 
places the toner image of each color onto print media producing full-color prints 
through three transfer units (primary transfer units [IDT1 (2 ea) and secondary 
transfer unit IDT2 (1 ea)].
