Abstract
A multi-nozzle ink jet printer adapted to eject ink droplets from arrays of nozzles and to charge the ejected ink droplets in a predetermined quantity. The charged ink droplets are deflected in the direction substantially parallel to the nozzle array so that the ink droplets can strike against a recording medium for printing. A deflection electrode assembly comprises a number of conductive wires stretched perpendicular to the nozzle array in a spaced relation, and the conductive wires are connected on alternate wires to form two groups between which a deflection voltage is applied.
