Abstract: A method of processing phase signals for continuous inkjet printing, said method comprising: providing at least one phase signal, wherein said at least one phase signal is an analogue signal; converting the at least one phase signal into at least one corresponding digitised phase signal; and processing said at least one digitised phasing signal, wherein the processing comprises extracting at least one predetermined phase parameter from the at least one digitised phasing signal when the at least one digitised phasing signal is a time-domain digitalised phase signal, and wherein the at least one predetermined phase parameter comprises one or more time-domain signal features of the at least one digitised phasing signal.

Abstract: A binary array ink jet printhead assembly includes a cavity for containing ink, nozzle orifices in fluid communication with the cavity for passing the ink from the cavity to form droplets, the nozzle orifices extending along a length of the cavity, and an electrode assembly. The electrode assembly includes a front face configured to be disposed generally parallel to a plurality of droplet paths of droplets from the nozzle orifices. A plurality of charge electrodes are disposed on the front face, each charge electrode corresponding to a droplet path and disposed parallel to the droplet path. Circuitry is disposed on the electrode assembly, wherein each electrode is electrically connected to the circuitry. The circuitry is further in electrical connection to a connector for connecting the electrode assembly to a controller for the printhead.
