Blank pages normally occur in duplex scanning when both sides of the page are scanned.
Image is not blank if it has black pixels after ignoring the following image elements:
Margins – Black pixels inside the following margin
- for sides larger than 7 inches the margin will be 1 inch
- for sides between 5 and 7 inches the margin will be 0.5 inch
- for smaller sides there will be no margin
Noise - Speckles of 5x5 pixels and smaller
Object – Single object smaller than 0.5 x 0.5 inch in size

Image should have correct values for vertical and horizontal resolution for proper calculations of margins and object size.
