See http://www.meier-geinitz.de/sane/genesys-backend/ .

I don't have any specific information about these scanners other than
what's mentioned in the scanner search engine.

The genesys backend is developed using the UMAX Astra 4500, which has
the same (or a very similar) chipset as the two HP scanners. With that
scanner the backend can reset the scanner, move forward and home the
slider, turn on the lamp and wait until the lamp brightness is stable.
The next step would be coarse calibration. Scanning some lines from
the calibration strip works, but the calibration code seems to be
wrong as the image gets too dark. The fine calibration after that
fails with a timeout for yet unknown reasons.
