Abstract
An ink jet printhead is provided with an orifice plate connected to the barrier layer, spaced apart from the substrate second major surface, enclosing the ink manifold, and defining a plurality of orifice apertures, each associated with a respective ink energizing element, wherein the orifice plate has a planar plate defining the plurality of orifice apertures and at least one groove. The at least one groove extends from an ink feed slot region of the inkjet printhead to a bubble collection area adjacent to an end firing chamber located beyond the ink feed slot region to facilitate guiding bubbles away from critical areas.
