Modeling of the Transient Heat Transfer in Xerographic Fusing Using a Discrete Element Approach
Abstract:In This study, a computer model, based on discrete element method, is used to simulate unsteady state heat transfer at the fuser/toner and toner/coating layer interfaces during the Xerography fusing process. The model coating layers consisted of randomly arranged spherical pigment and latex particles with commercially relevant size distributions. Effects of coating characteristics, toner size, multiple toner layers, toner melting energy and toner thermal conductivity on the unsteady state heat transfer in the fusing process were investigated. Results showed that temperature variation highly depended on the toner size, toner melting energy and the fuser roll temperature. Moreover, simultaneous coupling of the stress and heat transfer indicated that the pressure exerted by fuser roll cannot significantly affect the rate of heat transfer to the toner particles.

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.
