The picture below shows the film area guide for the Perfection 4990 Series / V700 / V750-M
PRO scanners with improper film placement. The film is too high on the bed and is covering
part of the white calibration notched area. Every time a film scan or preview is initiated, the
scanner will perform an incorrect white calibration reading which causes scanned images to
look “washed out” image or display lines.
