ABSTRACT:
A method is provided for adjusting the operating amplitude of a modulation signal which influences the separation of drops from an ink jet of an ink jet printer. The method includes (1) determining the phase relationship between the modulation signal and the instants when successive drops separate from the ink jet for a plurality of amplitudes of said modulation signal (2) identifying the amplitude of the modulation signal at a predetermined characteristic point in the function of the phase relationship with the amplitude from the magnitude of the change of the phase relationship with the change of the amplitude; and (3) selecting the operating amplitude for the modulation signal in accordance with the amplitude identified in step (2). An ink jet printer is also provided which has control means for identifying the predetermined point from the magnitude of change of the phase relationship between the modulation signal and the instants when successive drops separate from the ink jet with change in the amplitude of the modulation signal.
