Abstract
The present invention is an apparatus for tuning or altering the charge potential limiting effect that a scorotron grid has upon an adjacent charge receiving surface. The scorotron charging apparatus utilizes corona producing means, spaced above the charge retentive surface, for emitting corona ions in response to a high voltage potential applied thereto, and a flexible grid, suspended between said corona producing means and the charge retentive surface in a nonplanar fashion, such that the spacing between said grid and the charge retentive surface is variable along at least one region of said grid.
