Abstract:
1. A printhead assembly, comprising: at least one printhead module comprising a unitary arrangement of a support member, at least two printhead integrated circuits, each of which has nozzles formed therein for delivering printing fluid onto the surface of print media, at least two fluid distribution members each mounting the at least two printhead integrated circuits to the support member, and an electrical connector; a casing in which the at least one printhead module is removably mounted; and at least one controller provided on at least one printed circuit board supported by the casing and connected to at least one of the printhead integrated circuits via connection of at least one connection port of the printed circuit board and the electrical connector, the controller being configured to process print data and to communicate the processed print data to microprocessing circuitry of at least one of the printhead integrated circuits via the electrical connector so as to control the printing operation of said at least one of the printhead integrated circuits to print the processed print data, wherein the support member has at least one longitudinally extending channel for carrying the printing fluid for the printhead integrated circuits and includes a plurality of apertures extending through a wall of the support member arranged so as to direct the printing fluid from the at least one channel to associated nozzles in both, or if more than two, all of the printhead integrated circuits by way of respective ones of the fluid distribution members.
