High-speed Transfer Method for Colorprinter Using Dielectric Belt

Abstract

A high-speed color laser printer at a printing speed of 50 ppm has been developed. The printing process consists of four OPC drums each with a two-component developing unit and roller transfer through a dielectric belt.
This paper describes the transfer process theoretically and experimentally, based on the analysis of the equivalent circuit model. As a result, it is clarified that the transfer voltage is decreased by opposite polarity charge to the dielectric belt the transfer roller.
We have obtained the most suitable method to design the transfer process in the color laser printer.
