ABSTRACT:
In an ink-jet printer head having a number of edge-shooter module assemblies arranged in a stack, each module assembly has first and second circuit modules with an inkjet printer module therebetween. The ink-jet printer module is, in turn, formed by first and second cover plates with a middle plate therebetween. Piezoactuators are disposed on the cover plates in registry with ink pressure chambers in the module assembly, the ink pressure chambers respectively being in communication with nozzle apertures disposed at an edge of the module assembly. Various electrical components, including a driver circuit and conductor runs for operating the piezoactuators are disposed on the circuit modules in electrical contact with the piezoactuators.
