ABSTRACT:
A drive circuit for a piezoelectric transducer in an ink jet printer incorporates a resonant circuit formed of an inductance and a piezoelectric transducer functioning as a capacitance, with the resonant circuit being excited to oscillation by means of current pulses, and with such oscillation being damped by means of a damping circuit, said damping beginning after a time delay relative to the onset of said oscillation.
