Is bright sunlight or additional interior light shining directly on the white sheets?

Prevent bright light from being in contact with the white sheets, and then try scanning again.
Are the white sheets dirty?
Clean the white sheets .
For details about how to perform cleaning, refer to ScanSnap Help.
Were the white sheets covered by your hands or any other objects when the ScanSnap was turned on or when scanning started?
Scan the document again without covering the white sheets with your hands or with any other objects.
Is the computer in high contrast mode?
The ScanSnap does not support high contrast mode.
