<p>A vacuum cleaner for helping maintain the cleanliness of the exposed surfaces of an ink jet droplet ejector. The vacuum cleaner is comprised of a top cover plate, having a plurality of air passages, that is located over a channel surface by spacers. A vacuum means draws the pressure in the defined volume between the top cover plate, the channel surface, and the spacers below the external pressure, whereby air is drawn into the defined volume through the air passages. The resulting air flow removes ink, dust, and debris from the vicinity of the exposed surfaces, thereby helping to maintain the cleanliness of the droplet ejector. The top cover plate and spacers are beneficially formed using silicon microstructure fabrication techniques. <IMAGE></p> |
