Challenges in Components Design for Transfer Subsystem in Electrophotographic Marking

Abstract

This presentation will describe work processes to develop new materials and enabling surfaces that provide improved subsystem performance in order to meet the needs for continuing improvement of key xerographic marking subsystems. The presentation will be in two parts. In the first part, the aforementioned work process will be described, beginning with the identification of transfer subsystem requirements for marking processes based on tandem architectures. The major emphasis will be placed on performance optimization requirements. The second part will show specific examples of transfer subsystem components including intermediate transfer belts and bias transfer rolls designs. Specific emphasis will be placed on the difficulties encountered in materials design for seamed and seamless intermediate transfer belts. The presentation will close with subsystem design challenges to optimize system interactions in the transfer nip impacting component reliability and image quality.
