The method includes the steps of sensing a spatial pattern of densities in the media along a scanned strip, saving the spatial pattern of densities during the initial pass to create a path map from {HEAD ~ the start position} to an end point, comparing subsequently sensed spatial patterns of densities to the path map, and following the path map to repeatedly and accurately position the media at {TAIL ~ any point} along the scanned path
