Method and system for non-contact powder image development

[0030]The presently described embodiments improve upon the prior noted wireless method(s) in at least the following respects: (1) a 5-stage jumping development cycle is implemented 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 the return impact on the donor and, therefore, toner abuse; and (2) a routine is used 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. In at least one form, the routine allows for an automation of the process.

[0031]In this regard, given a distribution of particle size and charge, detachment forces have to act over a wide range to overcome the nonlinear adhesion forces of the donor surface to fluidize particles. The contemplated momentary overvoltage serves to so detach the majority of particles with a high
