Patent abstract
An inkjet printhead with an array of nozzles formed on one side of a wafer substrate, an array of corresponding ink inlets formed in the other side of the wafer, each of the ink inlets individually associated with one of the nozzles and, a fluid path extending between each of the ink inlets and each of the ejection apertures respectively. With individual ink feed channels to each of the nozzles, there is a high level of fluidic drag that eliminates any ink pressure cross talk between adjacent nozzles.
