ABSTRACT:
An apparatus for cleaning foreign particles from an ink jet orifice plate assembly having a plurality of orifices and an ink stream input passage includes a liquid reservoir containing a quantity of cleaning liquid in which the ink jet orifice plate/dye cavity assembly is disposed, ultrasonic agitation means for imparting ultrasonic vibrations in the liquid to dislodge foreign particles from the orifice plate assembly, and means for simultaneously propelling a stream of the cleaning fluid inwardly (in a reverse-flow manner) through the plurality of outlet orifices to carry off dislodged foreign particles. The solid particulates are thereby removed from the assembled structure before it is placed in operation in the fluid jet printer. The method for ultrasonic cleaning is also disclosed.
