Abstract
The ink jet print head has a single module or a plurality of modules in a stacked construction and it operates on the edgeshooter or the sideshooter principle. A common supply conduit for the ink conduits of the ink jet printing chambers is provided. A ribbon conductor, which connects to the print head control is also embodied as an ink conductor, which communicates on one end with a common supply conduit in the ink jet print head and on the other with an ink tank. At least one ink conduit is formed into the ribbon conductor. The ribbon conductor comprises a first part, secured to the ink jet print head, and a second part, outside the ink jet print head. The two parts may merge directly with one another or be connected to one another by a plug connector. A pressure equalization diaphragm and a replaceable filter are provided in the transition region between the ribbon conductor and the ink jet print head.
