Abstract:
1. A printhead assembly comprising: an elongate channel member of a metal alloy; a flexible elongate fluid carrier positioned on a floor of the channel member, the fluid carrier defining a plurality of passages longitudinally extending along a length of the fluid carrier, the fluid carrier further defining a repeated pattern of holes on an external surface thereof, the holes providing fluid communication from outside the fluid carrier to respective passages of the fluid carrier; and a series of printhead modules mounted to the external surface of the fluid carrier, each printhead module including an upper micro-molding and a lower micro-molding, the lower micro-molding having an air inlet slot in fluid communication with one of the plurality of passages via a hole of the repeated pattern of holes, and the upper micro-molding having an exhaust hole aligned with the air inlet slot and through which air carried in one of the passages is expelled, wherein each repeated pattern of holes diagonally spans a width of the fluid carrier, and the repeated pattern of holes together span a length of the fluid carrier, and the air expelled through the exhaust hole facilitates repulsion of a print media from the printhead.
