Abstract

In a system or method for supplying print bars with a plurality of print heads with ink in an inkjet printer, a pressure source is activated in a flushing procedure in order to exert an excess pressure to the ink in intermediate tanks supplying ink to the print bars such that the ink is flushed through jets of a print head to be flushed in the respective print bar. The pressure source is shut off when printing. The ink in the intermediate tanks is transported to the print heads by means by hydrostatic pressure. In the event of an overflow of the intermediate tanks, overflowing ink is transported into an overflow container via a respective pressure line connecting the overflow container to the respective intermediate container.
