Abstract (en)
[origin: EP0671270A2] The ink jet print head has a two-sided surface structure for ink chambers (101,105) and corresp. channels on a central part (3), outer membrane plates and an arrangement for feeding and ejecting ink from a chamber associated with each nozzle. Different structures are formed on the opposite sides of the central part so that at least two groups of chambers are at a distance apart in the x, y and z directions. The nozzle channels leading to a single row of nozzles (1) are formed on one side of the central part. The central part has vertical and horizontal ink channels so that there is a relatively short ink path from the chambers to the row of nozzles.
