Abstract
An ink jet printer having a drop generator for directing streams of ink droplets through deflection electrodes so that droplets travel to either a gutter or to selected regions on a printing medium. The gutter is constructed of a first low surface energy material such as parylene coated to a high surface energy material such as stainless steel. Only a portion of the steel is coated so that a boundary between high and low surface energy material is contacted by ink after it strikes the gutter. This boundary attracts the ink away from the gutter entrance due to capillary action and in a preferred embodiment is also aided by the force of gravity due to the orientation of the gutter.
