Abstract

A multiple drop stream ink jet or fluid drop recording method and apparatus is described in which at least every other deflection electrode includes a gutter or drop collection device inside the electrode. The recording system for which the gutter deflection electrode is intended is one wherein each of the multiple drop streams has a a pair of deflection electrodes associated with it thereby leaving minimal lateral and forward space for a gutter device. The gutter is hidden. That is, the mouth to the gutter faces downstream and is not accessable by drops in flight. Rather, drops first impact collision surfaces on the sides of a gutter deflection electrode. The resultant fluid surface stream flows around a curved end surface of the gutter deflection electrode and enters the gutter through the downstream facing mouth.
