Why do scanners produce blank pages?

Duplex scanners capture the back of every sheet, so single-sided documents end up with an empty page between each real one.

Will a page with just a page number be removed?

Only on the aggressive setting. The balanced default keeps anything with real content and removes only near-empty pages.

Automatically detect the blank pages in a scanned document and remove them. You can see exactly which pages will go before you confirm.
