Particle Simulation of Xerographic Line Images
Abstract:We use three dimensional particle simulations to explain how latent images of lines form in xerographic development systems. Our computational model uses the particle-in-cell technique to track toner particles in time and space under the influence of the numerous forces of xerographic development. Using physically realistic models of toner adhesion, cohesion, air drag, and friction; detailed particle trajectories can be calculated and monitored in selfconsistent electric fields. Examples of thin isolated lines, both parallel and perpendicular to the process direction, are analyzed for variations in mass and charge density. Details of the development process are shown to affect the image quality of individual and grouped lines (i.e., ladder charts). Excellent agreement has been observed between simulated development subsystems and experimental data.

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.
