Often functions exactly like an SPDF, meaning it captures both sides in one motion.
If you are choosing between a device labeled with SPDF versus a traditional DADF/RADF, here is how they compare: SPDF / Single-Pass DADF Traditional RADF (Reversing) Scanning Speed Much Faster (up to 270 ipm) Slower (requires mechanical flipping) Mechanical Wear Lower; few moving parts Higher; more rollers and flipping parts Paper Safety Safer for fragile or thin paper Higher risk of jams due to paper curling Best Use Case High-volume offices, large batches Occasional or low-volume duplexing Why SPDF (Single-Pass) is Typically "Best" difference between spdf and dadf best
Choosing the right document scanner or multi-function printer (MFP) often comes down to three acronyms: SPDF, DADF, and RADF. While they all automate scanning, the technology they use affects your office’s speed, reliability, and document safety. Often functions exactly like an SPDF, meaning it
(also known as a single-pass DADF) scans both sides of a page simultaneously in a single pass, whereas a standard (also known as a single-pass DADF) scans both
For a modern business, an SPDF or DADF is almost always the better investment for several reasons:
