ABSTRACT:
Provided is a printhead assembly for a pagewidth printer. The assembly includes a substrate channel, and a plurality of printhead modules positioned in the channel to form a pagewidth printhead module assembly. Also included are an extrusion for housing bus bars operatively providing electrical power to the printhead modules, and a cover plate securing a flex printed circuit board (PCB) in the assembly, the PCB forming a data bus to the printhead modules. The assembly further includes compressible conductive strips between the busbars abutting contacts on an upper side of parts of the flex PCB, wherein the substrate channel defines a series of groups of holes through which the printhead modules are supplied with differently colored inks.
