ABSTRACT:
A printhead assembly for a pagewidth inkjet printer includes an elongate support structure. A plurality of elongate printhead modules is positioned, end to end, in the support structure. Each printhead module includes a feed member that defines a number of longitudinally extending flow passages in fluid communication with respective flow passages of adjacent feed members and a number of ink outlet holes in fluid communication with each of the flow passages. A lower micro-molding is mounted on the feed member. The lower micro-molding includes a number of inlets in fluid communication with respective ink outlet holes and a number of exit holes in fluid communication with respective inlets. An upper micro-molding is mounted on the lower micro-molding and defines a recess and a number of ink passages in fluid communication with respective exit holes and terminating at the recess. A printhead chip is positioned in the recess to receive ink from the ink passages. A mid-package layer is interposed between the upper and lower micro-moldings and has adhesive to provide adhesion between the upper and lower micro-moldings.
