Printhead assembly incorporating laminated ink distribution stack

Abstract

An elongate printhead assembly for a pagewidth printer includes a printed circuit board (PCB) having mounted thereon various electronic components to facilitate operation of the printer; one or more printhead integrated circuits, each angularly disposed with respect to a longitudinal axis of the PCB; one or more printed circuit interconnections for providing signal communication between the one or more printhead integrated circuits and the electronic components; an ink distribution molding for receiving ink from an ink reservoir, the ink distribution molding having defined therein a plurality of ink ducts and a plurality of transitional ducts provided below the ink ducts, the ink ducts and transitional ducts being connected via ink transfer ports; and a laminated stack arranged between the ink distribution molding and the one or more printhead integrated circuits, the laminated stack having defined therethrough a plurality of ink holes for feeding ink to the printhead integrated circuits. The transitional ducts are angled acutely with respect to the ink ducts to align with the plurality of ink holes.
