ABSTRACT:
A high performance ink jet is operated in a fill-before-fire mode. The ink jet is characterized by at least one resonant frequency in excess of 10 kHz creating an upper limit for a frequency of stable operation. During operation, the ink jet is characterized by ejecting droplets of substantially equal velocity and/or size for various frequencies in an operating range extending from 0 to a fequency equal to or in excess of 5 kHz.
