Inkjet Printhead
Abstract:
An inkjet print head for generating a droplet of ink includes an ink supply substrate having an ink supply channel; a droplet forming unit arranged on the ink supply substrate; and a manifold chamber formed over an ink inlet surface of the droplet forming unit. The manifold chamber has a first wall formed by the ink inlet surface, a second closed wall formed opposite to the first wall and a side wall extending between the first wall and the second wall and surrounding the manifold chamber. The manifold chamber extends in a manifold plane. A manifold supply channel is arranged in the manifold plane and surrounds the manifold chamber. The ink supply channel is in fluid communication with the manifold supply channel. A number of manifold feed openings in the side wall provide for a fluid connection between the manifold supply channel and the manifold chamber.
