Abstract
An electrostatographic printing machine having an imaging member with a surface voltage potential and a control system including first and second reference values. A sensor measures first and second surface voltage potentials that are compared to the first and second reference values to provide first and second error signals to control first and second process stations in the printing machine. A first compensator responds to the first error signal to provide a first weighted adjustment to the first process station and a second weighted adjustment to the second process station. A second compensator responds to the second error signal to provide a first weighted adjustment to the second process station and a second weighted adjustment to the first process station in order to compensate for coupling effects between adjustments to either the first or second processing stations.
