Just for your information. I got the scanner working in grayscale in duplex by using saned and my Java Program which uses the Sane Network Protocol.
I am setting up a website to host the work done by me for using the Sane Network Protocol from Java. Once I have put some documentaion together and uploded it to the website I will let the list know the address.
