Automatic Image Cropping
This scanner has a built-in cropping function that detects and crops
dark edges of an original during the scan process. See the illustration
below.
NOTE : When scanning darker originals (for example, a photo
of the night sky), over-cropping may occur. Please insert the
original in a different direction (orientation) and try again.
