Abstract
A printing machine of the type including an image receiving member having a charge retentive surface with a first developed image being disposed in a first zone and a second developed image being disposed in a second zone is provided. The printing machine preferably including a corona generator positioned adjacent the charge retentive surface and characterized by an electrical parameter; a first control device for setting the electrical parameter to a first level for disposing the first developed image at a first charge level as the first developed image is passed by the corona generator; a second control device for changing the electrical parameter to a second level for disposing the second developed image at a second charge level as the second developed image is passed by the corona generator; and a cleaning member, contacting the charge retentive surface, for substantially removing both the first developed image and a portion of the second developed image from the the charge retentive surface, wherein the capacity of the cleaning member to remove the first developed image and the portion of the second developed image from the charge retentive surface depends on the magnitudes of the first and second levels.
