Abstract
A fluid jet device for depositing drops of fluid on a fluid receiving medium includes a print head means which defines a fluid receiving reservoir and which has a row of orifices communicating with the reservoir. Fluid is supplied to the reservoir under pressure and flows through the orifices to produce a row of fluid filaments. The fluid filaments are stimulated to break up into jet drop streams directed at the fluid receiving medium. The fluid in the reservoir is maintained at a predetermined electrical potential. An electrically conductive catcher means extends substantially parallel to the row of jet drop streams and electrically charges the drops formed from each of the filaments when a charge potential, differing from the predetermined electrical potential is applied to the catcher means. The charged drops are attracted toward the catcher means such that they are caught and prevented from striking the fluid receiving medium. Drops which are not charged by the catcher means travel past the catcher means and are deposited on the fluid receiving medium.
