Abstract: A method for controlling the feed of sheets to a sheet-fed printing press is provided for a sheet feeder unit comprising an individual drive assigned to each of a plurality of components provided for supplying the sheets in a stack, separating the sheets from a stack and supplying the sheets to the press. The method includes stopping at least two of the individual drives in a predefined position in a targeted manner when shutting down the feeder unit. The individual drives are operated in synchronization with one another during printing operation. The synchronization between the at least two individual drives is canceled when the sheet feeder unit is shut down. These drives are shut down individually and synchronized with one another when the sheet feeder unit is started up again such that in shutdown, each individual drive assumes a predefinable position.
