Page 56: Phaser 6128Mfp Operational Overview
Theory of Operation Phaser 6128MFP Operational Overview The Phaser 6128MFP is a full-color multifunction 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.

Page 59: Exposure
The area on the surface where the laser beam strikes becomes conductive. The negative charge on the surface flows to the more positive drum, lowering the voltage potential. In this way the surface areas exposed to the laser beam become the electrostatic latent image. Phaser 6128MFP Service Manual...

Once the toner adheres to the drum, the negative charge of the toner-bearing location increases, which decreases the potential and the toner-attracting force. Phaser 6128MFP Service Manual...
