Patent ID: 7945182

Claim:
An electrostatic image forming apparatus, comprising: a charge receptor, movable in a process direction, defining a main surface; a toner application device for applying toner to the charge receptor, and configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time; a primary cleaning device for cleaning the main surface of the charge receptor, the primary cleaning device including at least one pre-clean corotron influencing the main surface of the charge receptor; a secondary cleaning device configured to engage the main surface of the charge receptor downstream of the primary cleaning device; and a control system configured to reduce an influence of the at least one pre-clean corotron on the charge receptor, during selected rotations of the charge receptor, while the portion of the main surface on which the lubrication stripe is formed is passing the at least one pre-clean corotron, wherein the reduction of the influence of the at least one pre-clean corotron on the charge receptor reduces a cleaning efficiency of the primary cleaning device on the lubrication stripe by approximately 3%.
