摘要： A method of driving an electromechanical converter of a print head of a continuous inkjet printer, wherein the electromechanical converter is arranged to break up a continuous stream of ink into a plurality of drops.

摘要： A droplet generator for a multi-jet CIJ printhead that has an ink chamber with plural orifices for the emission of fluid streams. An actuator drive armature is disposed within the ink chamber and, at one side, has a one-piece solid drive wall with a pair of major faces which are tapered towards one another in the direction away from the other side. At the other side there is only a single pair of transducer mountings disposed adjacent the ends of the drive wall.

摘要： A method for adjusting the amplitude of the pressure modulation waveform in a multi-nozzle continuous jet printhead having a pressure modulator for causing streams of ink emitted from the nozzles to be broken up into individual droplets, and charge electrodes and change electrode controllers for controllably applying a charge to individual ones of the droplets in each stream. The method involves generating a modulation waveform to operate the pressure modulator to cause droplets to be generated in each stream, operating the charge controllers to supply a charge signal waveform to each charge electrode; and periodically determining the phase relationship between the charge signal waveforms applied by the charge controllers and the pressure modulation waveform to achieve satisfactory charging of the droplets, determining the spread of the phase relationships to achieve satisfactory charging of the droplets, and thereafter incrementally adjusting the amplitude of the pressure modulation waveform upwardly or downwardly to optimize the break-up length of the droplet streams.
