I've read a lot information about the new Canon scanner 2400, but nobody seems to give any information about the Canon scatch/dust filter on it. If any of you are using this scanner I would love to have some information (does it work?) on this option or feature on the Canon scanner. I've been thinking about getting one for scanning 4x5 chromes to print at home with my Epson 1280 printer. I know that it's not a drum scan...but I think for t he money it would do the job very well.Thanks for your help in advance.
