Abstract

In a printing machine having at least one transfer device driven in response to an electrical signal and operable to transfer a medium onto a sheet, a method controls the magnitude of the electrical signal driving the transfer device. The method includes assigning a magnitude of the electrical signal for driving the transfer device to each of at least two transfer stress levels, evaluating only operating parameters of the printing machine that have a pre-determined priority value relative to a corresponding pre-determined threshold value, selecting one of the at least two transfer stress levels based on the evaluation of the at least one operating parameter, and applying the magnitude of the electrical signal corresponding to the selected stress level to the electrically-driven transfer device.
