Method And System For Non-Contact Powder Image Development

International Classification:
G03G 15/08 G03G 15/06
US Classification:
399266, 399 55
Abstract:
An improved method and system for non-contact powder image development are provided. The present technique implements a 5-stage jumping development cycle where the initial stage is a momentary over-voltage condition to release the majority of the toner on a donor substrate and the final stage includes the implementation of a decelerating potential to minimize return impact on the donor and therefore toner abuse. It also uses a routine to directly determine improved (e. g. up to optimal) waveform amplitudes and pulse widths based on toner size and q/m, guided by physical insight.

Abstract:
An optically based transport system and method for transporting particles across a virtual electrode array are disclosed. The system comprises a photoconductor layer where optically induced electrodes are projected thereon through sequential light images in a traveling wave grid pattern in order to transport particles across the virtual electrode array with a traveling wave.
