Abstract
Inkjet printhead chips comprise a substrate, a plurality of transducers, a plurality of interconnects and driver circuitry capable of electrically connecting the transducers and the interconnects. The substrate has a surface with opposing first and second edges, with a plurality of transducers arranged along the first edge and a plurality of interconnects arranged along the second edge. The driver circuitry is arranged on the substrate. The printhead chips can also be included in inkjet printhead chip assemblies wherein the printhead chip is arranged on a print surface of a body, and wherein the print surface is capable of being arranged generally parallel to a surface of a print-receiving medium. In this embodiment, an edgefeed is disposed between the first edge and the printhead body, and is in fluid communication with an ink reservoir. At least one chamber is in fluid communication with the edge feed and a plate is provided with a plurality of apertures, each aperture being capable of cooperating with at least one of the at least one chambers to allow ink to be ejected from the at least one of the at least one chambers.
