Did you configure the settings in the scanner driver to scan in black & white mode?

Solution

Use a scanner driver to configure the scan settings that do not "binarize" (output in black and white), and then perform a scan.

The scanned image may differ from the original image significantly if you simply "binarize" (output in black & white) a picture or a photo.

Are the glass and rollers inside the ADF clean?

Solution

Clean the dirty parts.
