Every scan includes:

  • Update firmware via manufacturer tool or the ScanSnap/Fi updater.
  • Calibrate ADF rollers if prompted and run test scans.

    • | Scanner series | Max speed (ppm) | Supported raw modes | |----------------|----------------|----------------------| | fi-7460 / 7480 | 60 ppm @ 300dpi raw 16‑bit | Grayscale, IR (with mod) | | fi-7800 / 7900 | 110 ppm @ 600dpi raw | Full RGB + UV, 48‑bit | | SP‑1130 (flatbed) | N/A (single sheet) | Sub‑pixel stitching, 21µm mode | Fujitsu Scandall Pro V2.0 21
