Optimizing Developer Roll Design for Increased Component Life
Abstract:Developer roll design variables including roll compliance, coating hardness, and topography were evaluated relative to toner filming and photoconductor (OPC) wear; two common end of life failure modes in contact development laser printer systems. It was found that reduced coating hardness offered the greatest potential for minimizing toner filming. With respect to OPC wear, trends indicate that both overall developer roll compliance and topography can influence the usable life of the photoconductor; with softer rolls and a peaked topography preferred.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
