A plurality of serially arranged printhead modules is mounted on the ink reservoir. Each printhead module includes an ink chamber structure that defines a number of ink chambers and complementary feed openings that engage respective feed openings of the ink reservoir so that each ink vessel is in fluid communication with a respective ink chamber. A printhead chip is mounted on each ink chamber structure to receive ink from the ink chambers.
