An arrangement for supplying ink to a print bar with small pressure fluctuations may include an ink reservoir and a damping vessel. The print bar may include at least two print heads and is connected with the ink reservoir via a supply line. Each of the print heads is connected with the damping vessel via at least one damping line. The damping vessel is connected with a discharge line. The end of the damping line ends at a first height in the damping vessel. The end of the discharge line ends at a second height above the first height in the damping vessel. The arrangement may supply ink to the print bar with small gas fraction in the ink.

A cover for covering the nozzle plate of a print head while in a parking position to delay a drying of ink. The cover can clean the nozzle plate while the nozzle plate is covered. A cost-effective and installation space-efficient cleaning of the nozzle plate of a print head is thus enabled.
