Ink flow control system and method for an ink jet printer.

摘要

A piezoelectric pump 22 or equivalent transducer is mounted on or within an ink jet printhead and is used to modulate the frequency or amplitude, or both, of oscillations of a liquid meniscus at a liquid ejection orifice 17 of a nozzle plate 16. The liquid meniscus at the orifice 17 has a natural resonant frequency and amplitude with respect to its equilibrium position 19, and the above modulation is performed in a controlled timed relation with respect to the phase of the natural oscillations of the meniscus at the liquid ejection orifice 17.
