The single-pass DADF C1 and DADF BA1 offer two distinct approaches to document processing in your office. The single-pass DADF C1 is particularly efficient, scanning and copying both sides of a document simultaneously, ideal for fast processing. It supports a wide range of paper sizes, including A3, and adapts to your specific needs. The DADF BA1, on the other hand, processes documents single-sided, optimal for standard tasks and smaller jobs. This specific feature makes it an excellent choice for everyday office applications.
