Scanner lingo explained: blank page detection
Blank pages can be useful as an additional back page for double-page printed documents, as separator page or as final page of a document. But sometimes they sneak in unintentionally due to a paper miss-feed during printing. They can be redundant in a digital document and even annoying.
As a result, most scanners offer “blank page detection” where the scanner automatically detects blank pages within the stack of documents. It scans them anyway but won’t include them within the digital document.
Blank page detection saves storage space and improves readability for the electronic documents.
