Abstract
A continuous inkjet system includes a plurality of nozzles producing a respective liquid jet through each nozzle. A stimulation device at each nozzle is responsive to different types of stimulation signals to produce a modulation in the respective liquid jet to selectively control droplet break off relative to phases of the cycle of a varying voltage source that is connected to a charge electrode. The break off phase of a droplet relative to the voltage phase of the voltage source will determine whether the droplet is charged or not charged. Droplets that become charged may be deflected from their paths and a deflection mechanism including the charge electrode determines which droplets are allowed to reach a surface for say printing and which droplets are collected and not deposited upon the surface.
