ABSTRACT:
Provided is a pagewidth printhead assembly having a plurality of printhead modules. Each printhead module comprises a printhead integrated circuit (IC) having a plurality of ink ejection nozzles, and an ink distribution assembly formed from a stack of ink distribution layers, each layer defining apertures therein at predetermined locations, the layers laminated together so that the apertures of each layer complementarily define discrete ink distribution channels to the printhead IC. The module also includes air channels for directing air at the nozzles of the IC to purge unnecessary ink from said nozzles.
