I'm running OS X 10.4.11, and I cannot get either Image Capture or Preview to do their scan function. Neither program will recognize my Epson Stylus NX400 scanner/printer. Both programs just give me a message stating that the SANE program is in use by another application ( I downloaded some TWAIN SANE files for my version of Gimp, which also does not want to recognize the Epson). Help!
