Abstract:
A method for regulating an electrographic printing or copying process, comprising the steps of:providing an electrographic intermediate image carrier for receiving an intermediate toner image and wherein the intermediate toner image is later transferred onto a web-shaped recording medium in a shape of a web from a transfer printing surface at a transfer printing zone; generating a toner mark on the electrographic intermediate image carrier, sensing the toner mark to determine a measured density value based on the toner mark, and then removing the toner mark, a transfer of the toner mark onto the recording medium being prevented in a time span between the generation and the removal of the toner mark; regulating toner concentration at a development station with the measured density value; and generating information as said intermediate toner image on the electrographic intermediate image carrier and transferring the intermediate toner image onto the recording medium at the transfer printing zone from the transfer printing surface.
