ABSTRACT:
An ink-jet printhead includes a plurality of nozzles and ink channels arranged side by side, each nozzle being connected to an ink reservoir via its associated ink channel, and a plurality of electromechanical transducers, respectively, associated with each ink channel for pressurizing the ink liquid therein, so that an ink droplet is expelled from the nozzle. An active member is provided for compensating for the effect of the reaction force of each transducer by energizing at least one other transducer.
