ABSTRACT:
An apparatus for controlling the flow of ink in the nozzle of an ink ejector head, the latter having an ink flow system which has a chamber capable of being supplied with ink and a nozzle through which ink is ejected as well as a pressure producer capable of being subjected to pulses for applying pressure on the ink in the chamber so as to cause the ink to be ejected through the nozzle. The pressure producer has applied to it a series of pulses consisting of alternating primary and secondary pulses, the latter occurring a predetermined time interval subsequent to the cessation of the application of the immediately preceding primary pulse.
