Abstract:
A method for causing ink to be ejected from an ink chamber of an ink jet printer includes causing a first bolus of ink to be extruded from the ink chamber; and following lapse of a selected interval, causing a second bolus of ink to be extruded from the ink chamber. The interval is selected to be greater than the reciprocal of the fundamental resonant frequency of the chamber, and such that the first bolus remains in contact with ink in the ink chamber at the time that the second bolus is extruded.
