Abstract
A silicon body has an array of nozzles therein and a separate magnet for each nozzle integral with the body. The magnet is disposed adjacent the nozzle with which it cooperates so that it can apply a deflection, prior to break-up of the stream exiting from the nozzle into droplets, to selected portions of the stream. The droplets, which are formed from the selected portions having the magnetic deflection applied thereto from the magnet cooperating with the nozzle, deflect to a gutter and are not applied to a recording surface, which moves orthogonal to the nozzles. If desired, the winding of the magnet can have a second excitation frequency supplied thereto to break up the stream into droplets. The break-up of the stream into droplets also can be accomplished by vibrations produced by a piezoelectric transducer, for example.
