This setting is used with the Separate on blank page and Discard blank page options. In bytes, enter the file size of pages that are considered blank. A value of 1500 to 2500 bytes is considered normal for this setting.
Scanned pages should be similar in size when this setting is used. If a page has a file size below the Blank threshold value, the page is treated as a blank page.
This setting is available for all scan methods.
