3.6 Scan Dark Pictures
The scanner has a built-in cropping function that automatically detects and crops dark edges
and dark areas against the cropping baseline background during the scan process. To
prevent poor cropping, align the original straight against paper guides and ensure there is
adequate space in front of the feeder for the originals to completely feed through. Scanning
on a flat and uncluttered surface is recommended.
The following example illustrates a 4”x6” original photo scanned with auto-crop:
Original/Auto-crop on (default)
If the original is fed slightly crooked, the original is only cropped a pre-defined maximum
amount, as shown in the following illustration:
Max. 1.5mm
