An imaging system includes a cover having an underside with an identifiable pattern disposed over a platen. The imaging system is capable of recognizing the identifiable pattern and removing data from a digital image file of the scanned original corresponding to portions containing the identifiable pattern. An alternative imaging system provides for a preliminary scan that locates extraneous objects in the background of a scanned region. When an original is scanned, the digital image file from the scan of the original can be compared with the preliminary scan to remove extraneous images from the digital image file.
