Yes, It was caused by my HP printer Officejet 4500 scanner drivers or twain program not working properly. I uninstalled all of the HP programs and drivers, and then reinstalled them again. Now the scanner is working correctly, and I have a white background on my scanned documents.

Thanks for the hint.

Sounds like a scan that was configured to output an inverted image. If so, browse through the scanner's driver configuration / Acrobat scan configuration to untick the selection.
