Imagine dropping a 30-page contract into the feeder, pressing scan, and watching both sides captured in a single pass. This ADF assembly makes that routine. Built from high-grade plastic and metal, it withstands the wear of daily office use while maintaining precise alignment for streak-free scans. Whether you're digitizing invoices, copying reports, or faxing signed documents, the RADF mechanism reliably reverses each sheet for duplex output, cutting scan time in half compared to single-sided feeders.
