Zusammenfassung:	In some examples, a printing press includes a printing unit with at least four nozzle bars, each including a print head. At least one nozzle bar has a printing position and at least one service position. For instance, in a first service position, the at least one nozzle bar has a first distance to the transport path of a printing substrate, and in a second service position the at least one nozzle bar has a second distance to the transport path. The printing unit includes at least one cleaning device and/or cleaning system that is selectively arranged in an area between the at least one nozzle bar and the transport path. The at least one service position may be arranged in vertical direction above the printing position, and the second distance of the second service position of the nozzle bar may be less than in the first service position.
