A controller may detect an elevation of a recording medium that is to be printed to, the elevation may result in the printing element of a printing device being negatively affected. The controller may automatically produce a time-limited printing pause of the printing element in which the printing gap between the printing element and the recording medium is temporarily enlarged in order to direct the detected elevation past the printing element. A negative effect on the printing device given the presence of a damaged recording medium may thus be efficiently and reliably avoided or reduced.

Controller and method for operating a printing device given the presence of a recording medium elevation

In a print group for an ink printing apparatus, a housing is provided with print bars comprising print heads. The print bars are moveable independently of one another in a vertical direction from a printing position adjacent to a printing substrate into a park position and back. A protective flap bar for each print bar is provided which is pivotable and which is open to one side. The protective flap bar is arranged in a vertical position next to the print bar in the printing position such that the open side is facing away from the print bar. The protective flap bar is arranged in a horizontal position with the open side upward in the park position such that the print bar is engaged with its print head side in the protective flap bar.
