ABSTRACT:
A printing assembly has a chassis. A printhead assembly is mounted on the chassis and has printhead integrated circuits each with a plurality of micro-electromechanical nozzle arrangements for ejecting ink. An ink distribution assembly supports the integrated circuits. The distribution assembly defines a plurality of converging ink passages in fluid communication with respective ink nozzle arrangements. An ink reservoir is mounted to the ink distribution assembly and defines a plurality of parallel ink channels in fluid communication with respective groups of the passages, such that inks can be fed from the channels to respective groups of the nozzle arrangements. A paper feed mechanism operatively feeds paper past said printhead. A printed circuit board (PCB) has electronic components for controlling the feed mechanism and the integrated circuits.
