Abstract
An ink jet printer employs a wire mesh gutter electrode assembly and a wire mesh high voltage electrode, each having angled or skewed configurations geometrically related for providing a relatively narrow constricted path for ink droplets, so that charged and partially charged droplets, which are not used for imprinting, traverse a short path and are effectively captured and collected for recirculation and use in the ink recording process.
