Abstract:
Passively energized floating guide in a parked head scanner, to enable the original paper to clean a scanning glass slit wherein the scanning glass slit has a first end and a second end which are longitudinally opposing ends and wherein the paper crosses the scanning glass slit latitudinally moving from an entrance side to an exit side, comprising:a first end-plate one having a first slot, mounted to the scanner at the scanning glass slit first end; a second end plate having a second slot, mounted to the scanner at the scanning glass slit second end; and, a wiper bar having a wiper bar first end and an opposing wiper bar second end, and having a pivot point, wherein said wiper bar first end is pivotally attached at said pivot point to said first end-plate through said first slot, and said wiper bar second end is pivotally attached at said pivot point to said second end-plate through said second slot such that when at rest, said wiper bar rests on the scanning glass slit, wherein as paper passes over the scanning glass slit, the force of the paper causes said wiper bar to rotate slightly allowing paper to pass between said wiper bar and the scanning glass slit and passively energizes the wiper bar such that it applies pressure on the paper.
