Abstract
Wherein a plurality of ink jet nozzles are carried on a rotatable disklike member so that ink is ejected in a stream of droplets radially from each nozzle. Ink droplets are charged in a binary manner (i.e. charged or not charged) by a fixed array of charging members which are electrically switched so as to track a specific jet. Fixed deflection members delete charged drops from the ink droplet stream leaving neutral droplets unaffected. Print receiving material is wrapped with a slight skew around a stationary cylindrical shell and moved along a slight helical path on the cylindrical shell's surface. The shell encloses and surrounds the rotating disklike member, the fixed charging members, the fixed deflecting members and a suitably disposed fixed ink catcher. The neutral droplets of ink are adapted to pass through a bank gap in the cylinder such that the circular ink jet droplet scan effectively becomes a helical scan on the moving paper so as to produce line by line printing.
