ABSTRACT:
The present invention is a sample data control system having a toner dispensing control loop regulating toner flow using a sensor approach directly measuring developed images to eliminate toner mass variations, and a bias control loop maintaining optimum density images on the photoreceptor in spite of changing humidity conditions. Two test targets, each having two test patches are selectively exposed to provide test data in the photoreceptor image area for suitable sensing and control of the toner dispensing and bias control loops.
