  • Page 64: Phaser 6280 Printer Operational Overview

    Theory of Operation Phaser 6280 Printer Operational Overview 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.

  • Page 65: Printing Process

    Theory of Operation Printing Process The Phaser 6280 Printer print process consists of the following steps: Charging – The Drum surfaces are charged with electricity. Exposure – The Drums are exposed to laser beams. Development – Image is developed with toner.
