An electrophotographic printing machine having a latent image is recorded on a photoconductive member with the latent image being developed with marking particles, includes: imager for recording a test patch consisting of a solid patch; developer for developing the test patch with marking particles wherein the developed patch has a solid portion and an edge portion; sensor for measuring a density of the solid portion of the test patch; sensor for measuring a density of the edge portion of the test patch; a system for generating a first output signal corresponding to the density of the solid portion of the test patch; and a system for generating a second output signal corresponding to the density of the edge portion of the test patch.

TC runtime control using underdeveloped solid, and edge enhancement

In an electrostatographic development system wherein toner is conveyed from a donor member over a development gap to a charge receptor by a development field in the development gap, a method including the step of: monitoring at least a first parameter of the system to detect an arcing condition within the development gap; and if an arcing condition is detected, tuning a duty cycle to avoid the arcing condition.
