kimphot 0 Posted January 14, 2005 Just reformatted HD, installed Win XP pro and then SP2. I can't get the 1640SU scanner to function. All files seem to be in place.When I try to access the scanner I get "Could not open the TWAIN source. Make sure there is a valaid source for your scanner in the TWAIN directory found in the Windows directory." I've uninstalled and re-installed both scanner and PhotoShop. I've changed USB cables. Is there a known problem with XP SP2 in respect to my scanner. I would send an e-mail to support Epson but the last one I sent four years ago has yet to be answered!

zen69x 0 Posted March 26, 2005 I've got this very same scanner running under Windows Server 2003. Go here: http://www.epson.com/cgi-bin/Store/suppo...latform=Windows and grab the latest, 5.71a TWAIN driver. Also, I'm not entirely sure as I have it running, but you may need the Windows Image Aquisition service to be running for it to work as well. Share this post Link to post
