Abstract

Generally, in ink jet charging schemes, a single electrode, positioned at the jet's break-off point, is used for charging selected droplets. As set forth herein, droplet charging is accomplished by electrostatic induction through the application of a potential difference between the electrode and the ink reservoir (the head). The required charge flows through the continuous jet so that when a droplet breaks off it carries with it a charge proportional to the applied voltage.
