Abstract
An apparatus for use in an ink jet recording device or printer for cleaning or protecting the nozzles in a writing head is disclosed. The apparatus comprises rotatably mounted supply and take-up reels; a movable absorbent cleaning belt extending from the supply reel to the take-up reel, the belt including a plurality of embossed elements and a plurality of openings positioned in sequence along the belt for being brought into contact with the nozzles; and a sensor for sensing the positioning of openings in said belt over said nozzles and thereby controlling movement of the belt to permit the embossed elements to be drawn across the nozzles to clean ink and impurities therefrom until the next openings are positioned over the nozzles whereby the sensors cause the belt to cease movement and permit the ink jet writing heads to print through the openings.
