Abstract
A print head for a continuous ink jet printer has a nozzle 5 through which ink is emitted and broken up into droplets under the action of a piezoelectric oscillator. A charge electrode 3 applies charge to selected droplets and a deflection electrode 4 deflects the path 20 of the charged droplets to cause printing on a substrate. A gutter 6 collects droplets which are not required for printing. A charge electrode 3, together with one of the deflection electrodes 4 is movable in a direction transverse to the path of the droplets selectively under the action of pressurised ink fed from an ink supply 14. Similarly, the gutter 6 is movable in the same way.
