Abstract
In a xerographic printer, a transfer station is controlled to apply a constant current to the photoreceptor. A print sheet having a high moisture content will cause the control system to make a high voltage drain to maintain the constant current. A signal related to the voltage drain is used to control a decurler. The system enables the decurler to be controlled on a sheet-by-sheet basis.
