Duplex scanning is a technology that allows a scanner to capture images from both sides of a document simultaneously. This feature is particularly useful for efficiently digitizing double-sided pages, such as contracts or reports, without the need to manually flip the pages. By using duplex scanning, users can save time and reduce the number of scans needed, making it an ideal choice for offices and individuals who frequently handle multi-page documents. Many modern document scanners come equipped with this capability, enhancing productivity and streamlining the scanning process.
