Abstract:
1. A printhead module for a printhead assembly, comprising at least two printhead integrated circuits, each of which has nozzles formed therein for delivering printing fluid onto the surface of print media, and an elongate support member adhesively supporting the printhead integrated circuits via individual fluid distribution members for each printhead integrated circuit, wherein the support member has a plurality of longitudinally extending channels for carrying different printing fluids for the printhead integrated circuits, the support member is selectable to meet specific requirements as to the number of said printing fluids to be employed for printing, and each of the fluid distribution members incorporates a laminated stack of layers, each layer having apertures for distributing the printing fluid from the support member to the associated printhead integrated circuit the apertures of each layer from the support member to the associated printhead integrated circuit being of successively smaller diameter.
