Abstract
Apparatus and method for scheduling toner patch creation at a first frequency and monitored for implementing diagnostics for a color image processor's systems parameters and system fault conditions in a manner that minimizes the waste of toner materials without compromising image quality. In the presence of a fault condition the toner patches are created at a different frequency. The number of toner patches required for the control is reduced through the use of complementary color toner patches in lieu of use of color patches for each individual toner colors.
