Your scanner can scan at 4800dpi optical. However, the support level of the epkowa (and epson) backend only allow settings in the list you included :-( The iscan frontend does the other ones in software. To add support for resolutions > 3200 modifications in both the frontend as well as the backend are required. If you want this supported, I suggest you file a support request with pipsnews at avasys.jp Hope this helps, -- Olaf Meeuwissen EPSON AVASYS Corporation, SE1 FSF Associate Member #1962 sign up at http://member.fsf.org/ GnuPG key: 6BE37D90/AB6B 0D1F 99E7 1BF5 EB97 976A 16C7 F27D 6BE3 7D90 Penguin's lib! -- I hack, therefore I am -- LPIC-2
