Abstract: An impression station of a printing system comprises a rotatable impression cylinder with an impression cylinder gap housing a plurality of grippers recessed therein. A pressure cylinder assembly comprises a pressure cylinder comprising a pressure cylinder gap and an angle portion joining a trailing edge of the pressure cylinder gap and an outer circumferential surface of the pressure cylinder. A compressible blanket is disposed around the circumference of the pressure cylinder. A margin insert is interposed between the pressure cylinder and the compressible blanket at least at the angle portion, such that a local external geometry of the pressure cylinder assembly at the angle portion is changed by the presence of the margin insert. The change in the local external geometry of the pressure cylinder assembly due to the presence of the margin insert is effective to reduce a dimension of an unprinted leading-edge margin.

Abstract: Devices include electrically conductive elements contacting a vacuum belt, and a voltage source connected to the electrically conductive elements. The electrically conductive elements form an electrical circuit from the voltage source, through the belt, and back to the voltage source. The electrically conductive elements are positioned so that they are separated from the belt when the belt moves the sheets of media between the electrically conductive elements and the belt. A processor is capable of identifying leading edges of the sheets of media on the belt (when voltage of the electrical circuit changes from a relatively higher voltage to a relatively lower voltage) and identifying trailing edges of the sheets of media on the belt (when the voltage of the electrical circuit changes from the relatively lower voltage back to the relatively higher voltage).
