Method of manufacturing a four color modular printhead

摘要

A method of manufacturing a printhead assembly includes selecting a printhead sub-assembly, the printhead sub-assembly comprising a printhead chip and a film electrically connected to the printhead chip. The printhead sub-assembly is attached to a printhead molding and a cover molding to form a print module. An ink reservoir sub-assembly is formed and a plurality of the printhead modules are attached to the ink reservoir sub-assembly in end-to-end relationship. Ink is charged into the reservoir sub-assembly and the completed assembly can be tested.
