Brother DS-640
Score: 72/100Rankings
The Canon CanoScan LiDE 400 provides ultra-high 4800 × 4800 dpi resolution and rapid 8-second A4 scans via USB-C. Without an ADF and limited to USB connectivity, it serves home users and photographers needing high-detail flatbed scans.
The Brother DS-640 is a compact, USB-powered scanner delivering 600 dpi color scans and built-in OCR, ideal for mobile, occasional scanning tasks. Its lack of duplex capability and an automatic feeder limit its usefulness for higher-volume or double-sided work. Best suited for travelers and home-office users needing quick single-page scans.
