ABSTRACT:
Methods of and apparatus for compensating electrostatic printing process stations for residual toner voltage. A toner patch is produced on a photoreceptor. That toner patch and a section of the untoned photoreceptor are then charged and exposed so as to produce a first latent image. The residual voltage between the exposed toner patch and the exposed section of the untoned photoreceptor is then determined. At least one processing station is then adjusted to compensate for the determined residual toner voltage. Process stations which can be adjusted include development stations, exposure stations and charging stations.
