Abstract
An ink supply system includes a print head assembly and a print head with one or more nozzles for a color. The print head is connected with the nozzles via a first connection line. A supply tank is connected with an intermediate tank via a filler line under an interconnection of a feed unit and a filter assembly. The pressure difference of the ink flow from a return tank to the supply tank is controlled by the print head. A method cleans the ink supply system, and a method cleans the print head.
