Abstract
A liquid jet printing apparatus is provided having a nozzle for emitting a stream of liquid droplets toward a substrate, a charging section for providing an electrical charge to liquid droplets and a pair of electrically conductive deflection plates for creating an electrical field capable of deflecting the liquid droplets to a desired location on the substrate, wherein a resistor is provided between a power source and the electrical field to limit current from the power source during electrical arcing between the deflection plates, thereby minimizing disruption to the electrical field and minimizing electromagnetic pulses.
