ABSTRACT:
A method of adjusting stimulation amplitude in continuous ink jet printers to provide satellite-free printing includes the steps varying the stimulation amplitude between the underdrive and overdrive stimulation conditions, charging the resulting ink jet filaments at their break off points with sawtooth voltage of period equal to the stimulation period, detecting and storing the resultant drop charging events and setting the operating stimulation amplitude based on the inception point inflection in the resulting stimulation amplitude versus detected charge relation.
