Printhead assembly for an ink jet printer

摘要

A printhead assembly for an ink jet printer includes an elongate pagewidth printhead having a plurality of nozzle arrangements. The printhead defines a plurality of ink supply passages in fluid communication with each respective nozzle arrangement. An elongate pagewidth ink distribution manifold is connected to said printhead, the manifold being in fluid communication with the ink supply passages and defining a plurality of ink inlets. An ink supply unit is connected to said manifold and defines a volume in which ink for the printhead is stored while being fed from the supply unit to the printhead, via the manifold. The ink supply unit includes a plurality of obstruction members that are positioned in the ink supply unit to inhibit excessive movement of ink in the ink supply unit as a result of movement of the printer.
