摘要
A printhead assembly for a pagewidth printer includes a substrate channel; a plurality of printhead modules positioned in the channel to form a pagewidth printhead module assembly; an ink hose positioned within the substrate channel to supply the printhead modules with ink; an extrusion for housing bus bars providing electrical power to the printhead modules; a cover plate securing a flex printed circuit board (PCB) in the assembly, the PCB forming a data bus to the printhead modules; and compressible conductive strips provided between the busbars abutting contacts on an upper side of parts of the flex PCB. The substrate channel defines a series of groups of holes through which the printhead modules are supplied with differently colored inks. The hose defines parallel channels extending a length of the hose, the channels connected to ink containers at one end and sealed with a channel extrusion cap at the other end.
