Printhead assembly with a laminated ink distribution assembly

摘要

A pagewidth inkjet printhead assembly includes an elongate ink distribution arrangement that defines a number of inlets, a number of corresponding ink distribution channels and a number of outlets in fluid communication with respective ink distribution channels. An elongate ink distribution assembly is mounted on the ink distribution arrangement. The ink distribution assembly has a plurality of layers together forming a stack. The layers are configured to define a plurality of inlets in fluid communication with the outlets of the ink distribution arrangement and mounting formations with passages opening into the mounting formations. The passages are in the form of ink passage sets in fluid communication with respective ink distribution channels. At least one passage from each set opens into each mounting formation. Printhead integrated circuits are mounted in respective mounting formations to receive ink from the passages.
