  • Patent number: 6243908
    Abstract: A card is provided for cleaning a document track of a document handling system, and methods for making and using the same. The card includes a planar body formed of a resilient material, such as a fibrous or polymeric material. The body includes a plurality of tabs, with each one of the tabs being pivotable relative to the body between an extended position and a collapsed position. In the extended position, the tab projects angularly from the body, while in the collapsed position, the tab is substantially co-planar with the body. The tabs are biased to the extended position, such as by creasing the material forming the body. The biased tabs extend across the document track, and sweep debris along the document track.
