Abstract
A drop-on-demand printer system has a print head including a manifold plate and one nozzle plate for each desired printing nozzle array. The manifold plate carries dot valves each controlling the flow of ink to one nozzle of each array. Ink passed by each dot valve flows through an outlet passageway to an opening. The nozzle plates each mount a nozzle array on a front side surface in linear columns with staggered nozzles. On each nozzle plate back side surface, grooves couple ink from one manifold outlet passageway opening to one nozzle. The manifold outlet passageway openings are located to be symmetrical at 180 degrees of rotation so that all the nozzle plates can be mounted on the manifold plate in either one of two positions rotated 180 degrees from one another.
