Abstract

An inkjet printhead assembly includes a molded plastics module defining a plurality of converging ink channels. Each ink channel has an inlet for receiving ink, an outlet and tapered sidewalls extending between the inlet and the outlet. Each outlet is defined in a mounting surface of the molded plastics module. A printhead chip is mounted on the mounting surface, which receives different colored inks from the outlets. The inlets are spaced wider apart than the outlets and the inlets have larger dimensions than the outlets.
