Printhead assembly with modular detachable printheads

摘要

A printhead assembly includes a chassis. An ink reservoir is mounted on the chassis. The ink reservoir defines a number of ink vessels for retaining respective inks, each ink vessel having a series of feed openings. 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. A TAB film is attached to the printhead chip to supply the printhead chip with power and control signals.
