P09503: Electrophotographic Development and Transfer Station


Table of Contents

Project Overview

The objective of this project is to make an existing electrophotographic development and transfer station (shown below) function and to improve its usability. Electrophotography (EP) is the base technology that is used in many modern day copiers and printers. Examples of manufacturers that use this technology in thier products include Xerox, Canon, Lexmark, and Hewlett-Packard, to name a few. Electrophotography a six step process that consists of uniformly charging a photoconductive material. Photoconductive materials allow charge to flow when exposed to light. EP products exploit this property by selective discharging areas on the photoconductor to form what is referred to as a latent image. When this latent image comes close to charged toner particles, these charged particles will transfer onto the latent image to form a developed image. Through the use of electrostatics, the image is ultimately transferred onto a media substrate (such as paper) and fused. The following link from Canon, while focused on color laser printing, gives an excellect overview of the EP process: | Canon Movie Link]
