Abstract
An inkjet print head includes an ink supply substrate having an ink supply channel in fluid communication with an ink supply connector channel for receiving ink from an ink reservoir and in fluid communication with an ink return connector channel for supplying ink to the ink reservoir; a droplet forming unit arranged on the ink supply substrate and having an ink inlet surface, in which ink inlet surface an ink inlet port for receiving ink from the ink supply substrate is arranged; a manifold chamber formed over the ink inlet surface of the droplet forming unit; and a filter arranged between the ink supply substrate and droplet forming unit. The filter has a first filter surface at an upstream side and a second filter surface at a downstream side. Filter holes extend from the first filter surface to the second filter surface. The first filter surface forms a wall of the ink supply channel.
