Device for positioning at least one print bar in a printing position in an inkjet printing apparatus

A method for positioning a print bar in a printing position in an inkjet printing apparatus, comprising the steps of:

• inserting the print bar into first and second drive and guidance units each of which comprise guidance units and such that arbors of the guidance units engage in receptacle bores of the print bar receptacles of the print bar, wherein a diameter of the respective receptacle bore is chosen to be larger than a diameter of the respective arbor, and wherein respective elastic units are screwed into the respective arbors via the respective print bar receptacles so that an elastic force is exerted on the print bar receptacles in a direction towards the guidance units;
• and
• in a positioning of the print bar in the drive and guidance units in said printing position, lowering the guidance units until positioning pins provided such that they can be displaced in the print bar receptacles engage in positioning plates arranged in the drive and guidance units, wherein the print bar receptacles detach from the guidance units, and the positioning pins are positioned in the associated positioning plates due to a weight of the print bar and the elastic force of the elastic units and thereby center and arrest the print bar in the drive and guidance units.
