Abstract: In a method to check a fixative print head for nozzle failures, a reference mark is printed by the nozzles of a colored ink print head and a test mark is printed via overprinting of the colored ink by the nozzles of the colored ink print head and of a fixative by the nozzles of the fixative print head onto a printing substrate web. The test mark and the reference mark are compared with one another. If the reference mark and the test mark correspond to one another (e.g., at least in part), this indicates that nozzles of the fixative print head are operating incorrectly. If operating incorrectly, the nozzles have, for example, failed entirely or eject the fixative at too great an angular deviation.
