Abstract (en)
Ink-jet printhead comprising a plurality of nozzles (12) and ink channels (16) arranged side by side, each nozzle being connected to an ink reservoir (14) via its associated ink channel, and a plurality of electromechanical transducers (40; 40') respectively associated with each ink channel for pressurizing the ink liquid therein, so that an ink droplet is expelled from the nozzle, characterized by active means (36, 38; 38') which compensate the effect of the reaction force of each transducer by energizing at least one other transducer (40, 44, 46; 40'). <IMAGE>
