A method for changing a relative position of at least one transport means (204) of an infeed system (202) of a sheet processing machine (01), the infeed system (202) comprising at least one cam mechanism comprising in each case at least one cam disk (212) and an axis of rotation (D) of the at least one cam disk (212), the at least one cam mechanism being driven by at least one drive (1001) via at least one drive shaft (1002), at least one scanning element (213) in each case resting against the at least one cam disk (212), the at least one scanning element (213) being connected to the at least one transport means (204) via at least one drive lever (214), the at least one drive lever (214) in each case having at least one mounting point (S), the at least one mounting point (S) and the axis of rotation (D) being adjusted relative to one another, the at least one mounting point (S) and the axis of rotation (D) being pivoted relative to one another, the at least one transport means (204) moving in and/or counter to a transport direction (T) by the at least one drive lever (214) being pivoted about the at least one mounting point (S), characterized in that a position displacement of the at least one mounting point (S) relative to the axis of rotation (D) compensates for at least one position error of at least one sheet (02), that the at least one mounting point (S) and the axis of rotation (D) are displaced relative to one another by at least one servo drive (218), and that the at least one servo drive (218) intervenes in a movement that is transmitted from the at least one drive shaft (1002) to the at least one transport means (204).
