Each printhead module includes an elongate printhead chip having a plurality of nozzle arrangements and defining a plurality of ink inlets in fluid communication with respective nozzle arrangements. An ink distribution assembly defines an elongate recess on one side in which the printhead chip is mounted, and a number of ink distribution conduits that converge from an opposite side to communicate with respective ink inlets of the printhead chip. An elongate ink feed member includes at least one longitudinally extending ink feed passage and a plurality of transverse openings in fluid communication with the ink feed passage and with respective ink distribution conduits in the ink distribution assembly. The ink feed modules are positioned on the support structure such that the ink feed passages of contiguous ink feed members are in fluid communication with each other.
