Because an SPDF images both sides of a document at the exact same time, its duplex scanning speed is essentially double that of a DADF. A DADF must pause, reverse the gear system, flip the paper, and re-feed it. If an office frequently digitizes large stacks of double-sided invoices, medical records, or legal contracts, an SPDF will save hours of administrative time. 2. Mechanical Reliability (Winner: SPDF)

are largely linear. The paper moves smoothly from the input tray straight through to the output tray. Fewer twists and turns mean drastically fewer paper jams. 3. Document Preservation
