Modular printhead assembly with respective flexible printed circuit boards

摘要

A printhead assembly for an ink jet printer includes an elongate carrier. An elongate ink supply structure defines at least one longitudinally extending ink passage and at least one set of holes in fluid communication with the at least one ink passage. The ink supply structure is mounted in the carrier and extends a length of the carrier. A plurality of printhead modules is mounted in the carrier on the ink supply structure. Each printhead module includes an ink distribution structure in fluid communication with the holes of the ink supply structure and an elongate printhead integrated circuit mounted on the ink supply structure to receive ink from the ink supply structure. A plurality of flexible printed circuit boards connects to respective printhead integrated circuits to supply the printhead integrated circuits with power and data.
