Two-dimension full array high-speed ink-jet print head

An ink-jet print head in a structure, similar to a liquid crystal display, is suggested. It is based on a segment, containing a microink reservoir, feeding one or a few nozzles. The segment is autonomous and unlimitedly duplicable to form a large ink-jet print head. The microreservoirs are open to the atmospheric pressure, and pressure regulation in the nozzle is accomplished by capillary action. The microreservoirs are replenished by slow wiper smearing action. Experiments with a 57600 nozzle matrix print head showed good results for the design. Printing speed of ~1000 pagesmin, and even more, is achievable.
