ABSTRACT:
An ink jet recorder of the type where ink from a plurality of nozzles is directed to a record medium for encoding of information onto said medium. The recorder includes scanning electrodes which deflect ink columns formed through the nozzles from side to side so each nozzle throws ink to a selected portion of the medium. At the point of ink droplet formation, charging electrodes induce either a positive or negative charge on each ink droplet. A quadrapole field generating electrode located intermediate the charging electrode and the record member deflects the charged droplets according to a scheme whereby the side to side scanning of positively charged droplets is amplified and negatively charged droplets are guttered and recirculated for reuse by the recorder.
