SCANSNAP

          A simple command-line tool that talks to Fujitsu ScanSnap
     iX500 scanners over WiFi. Put paper in, run the command, get a
     PDF. No daemon, no GUI, no dependencies beyond libc and pthreads.

          May also work with other ScanSnap models that use WiFi
     (iX1500, etc.) — reports welcome.


BUILD

          make


SETUP (one time)

          Your scanner is paired with a key — the serial number of
     its internal WiFi module. If the scanner was set up with the
     official ScanSnap Home app, that app knows the key, so we
     trick it into telling us:

     1. Turn off or disconnect the real scanner
     2. Run "scansnap --getkey" (needs ports 52217, 53218, 53219 —
        may need sudo)
     3. Open ScanSnap Home on your Mac or Windows machine — it will
        find the fake scanner and send the key
     The key is saved to ~/.config/scansnap/key automatically.
     You only need to do this once.


SCAN

          scansnap

          The scanner is found automatically on your local network.
     Pages come out as a timestamped PDF in the current directory.


OPTIONS

     -s IP       scanner IP (skip auto-discovery)
     -k KEY      pairing key from setup step
     -o FILE     output filename (default: scan_YYYYMMDD_HHMM.pdf)
     -j          save as separate JPEG files instead of PDF
     -1          single-sided (discard back pages)
     -d          debug output
     --getkey    capture pairing key (see setup)


HOW IT WORKS

          The scanner speaks a proprietary protocol ("VENS") over
     UDP and TCP. See the PROTOCOL file for the full reverse-
     engineered specification.
