Abstract

A printhead module includes: an ink manifold defining a plurality of ink supply channels, the ink manifold having first and second opposite faces; a plurality of print chips mounted on the first face, each print chip receiving ink from a respective ink supply channel via a set of ink outlets defined in the first face; first PCBs mounted on the first face of the ink manifold, each print chip being electrically connected to a respective first PCB; and second PCBs mounted on the second face of the ink manifold. The first and second PCBs are connected via electrical connectors extending through longitudinal slots defined in the substrate.
