Manufacturers like Xerox or Ricoh often use "SPDF" or "Single-Pass DADF" to highlight that the device does not need to reverse the paper. Standard "DADF" can sometimes refer to older "reversing" technology (RADF) in some contexts, so checking for "single-pass" capability is crucial.
This is the standard technology found in most entry-level and mid-range printers and scanners. A DADF has only (usually located at the top). difference between spdf and dadf best
Since the paper doesn't have to be pulled back and flipped, there is almost no chance of the paper crumpling or jamming during the "u-turn." 🔄 DADF: The Versatile Choice Manufacturers like Xerox or Ricoh often use "SPDF"
(specifically the "reversing" type often found in consumer models) usually scans one side, mechanically flips the paper, and then scans the other side. Comparison at a Glance SPDF (Single Pass) DADF (Reversing / Standard) Scanning Method Two scanners hit both sides at once Flips paper to scan front then back Speed Very Fast (2x speed) Slower (due to flipping) Noise Louder (mechanical flipping) Risk of Jams Low (straight path) Higher (reversing path) Price Premium / High-end More affordable ⚡ SPDF: The Performance Choice A DADF has only (usually located at the top)
