ABSTRACT:
A circuit connecting device for use with a digital printing apparatus is disclosed, the digital printing apparatus having a jet module assembly, a plurality of ink ejecting devices mounted in the jet module assembly, a corresponding plurality of ink ejecting nozzles formed on a nozzle plate mounted on an exterior of the jet module assembly, conduit means within the jet module assembly communicating between the ink ejecting devices and the nozzles, and a control electronics component for controlling the sequence of activation of the ink ejecting devices to cause ink to be ejected from the nozzles onto an image receiving medium during relative movement between the print head and the image receiving medium. The circuit connecting device has a pair of plates on which there is an electric trace pattern on the exterior surface of each plate and an electronic driver chip mounted on the exterior surface of each plate, and means for connecting the trace patterns to the electronic driver chips and to the control electronics component on the input end of the electric traces and to the ink ejecting devices on the output end of the electric traces, thereby eliminating all hard wiring between the control electronics component and the ink ejecting devices of the jet module assembly.
