Title: Stable substrate structure for a wide swath nozzle array in a highresolution inkjet printer

Abstract: An inkjet printhead includes a compact substrate of increased stability andstructural integrity to provide a high resolution 600 dot-per-inch nozzlearray having a one-half inch swath. A plurality of ink vaporizationchambers are respectively aligned with the nozzles in two longitudinalcolumns, one column extending longitudinally along one edge of thesubstrate and a second column extending longitudinally along an oppositeedge of the substrate, with ink feed channels communicating through an inkpassage from an underside of the substrate around both edges of thesubstrate to the vaporization chambers. The ink feed channels have therebybeen eliminated from the central portion of the substrate, and replaced bythe ink feed channels at the edges of the substrate.
