An ink jet print head face cleaner provides a controlled air passageway through an enclosure formed against the print face. Air is directed through an inlet into a cavity in a body. The body has a face with an opening into the cavity. This face is sealingly placeable against the print face. The cavity has a limited size so that air is directed without interruption through the cavity past the ink jet apertures, and out an outlet. The cleaner body is coupled resiliently to a platform to allow positioning of the body and print faces flush with each other. A vacuum source is preferably attached to the outlet to create a subatmospheric pressure in the cavity to further seal the two faces together. A collection chamber and removable drawer are positioned below the outlet to facilitate disposing of removed ink.

An apparatus for cleaning an aperture of an ink jet print head, which aperture is disposed in a face of the print head, comprising: a supply of cleaning fluid; a body coupled to said cleaning fluid supply and having a first face configured for placement against the print head face, said first face having an opening sized to surround the print head aperture when said first face is placed against the print head face, said body including a cavity extending along said opening, an inlet opening into and forming, substantially, a first side of said cavity adjacent to one edge of said opening and configured to direct the cleaning fluid into said cavity toward a position on the print head face upstream from the aperture, and an outlet opening into and forming, substantially, a second side of said cavity adjacent to a generally oppositely disposed edge of said opening, said cavity forming a substantially uniform and uninterrupted passageway from said inlet, along said opening of said first face, to said outlet, said passageway in said cavity having cross-sectional dimensions substantially the same as the dimensions of said inlet; means for moving said body so that said first face is placed against the print head face; and means for directing the cleaning fluid through said inlet into said cavity, along said opening of said first face, and out said outlet.
