ABSTRACT:
A fluid jet system for producing at least one jet drop stream includes a print head having a fluid receiving reservoir and an orifice plate provided with orifices communicating with the reservoir in such a manner that fluid supplied to the reservoir under pressure emerges from the orifices as fluid filaments. A transducer responsive to a drive signal applies vibrational energy to the orifice plate for stimulating breakup of the fluid fliaments into streams of drops of substantially uniform size and spacing. A drive circuit applies a substantially sinusoidal drive signal to the transducer for stimulating such breakup. Cleaning of the print head is accomplished by applying to the transducer a pulse train including harmonics of the sinusoidal stimulation drive signal.
