Abstract

Charging of imaging surface is non-uniform across surface. Previous efforts to improve on this include scorotron grids, corotron pins, etc. Individual pins of pin charging device can be controlled by independent circuitry to individual voltages with Feedback. This allows the individual pins to have the appropriate voltage to produce a uniform charge on the imaging device. This technique can be used with or without a (scorotron) grid between the pin charging device and the imaging device.
