I have a Sharp AR5220d - I've downloaded and installed correctly the TWAIN driver from Sharp's website.
Everything works smoothly but I'd like to use this scanner with a free application (better) or a small paid one like VueScan.
It works perfectly but since I'm unable to force the TWAIN driver utilization - I get fewer options and mainly I'm not able to use duplex.
Any hints on how to force the TWAIN driver?
