Can this device scan to an SD card, and if so, does the printer export that card as a network share? That's the approach I have to take with my Epson. I pick the resulting PDFs apart into TIFF scans and add good-enough OCR with Tesseract.

While I can get SANE to work for single page scans, it doesn't drive the ADF or duplexer properly.

Cheers
