I have been wrestling with this for a while now, and not turning up much through searching the web. I have installed SANE sane-backends-1.0.14 and have a CANON lide30 scanner. At low resolutions it will process fine. If I go to 300 is fails at about 75% and anyhting higher wont even start.
I had it working with an LIDE20 - until that unit crapped out - the optic bar would just pin itself to the edge and grind. I am connecting to the SANE backend via XSANE from a remote linux box as well as a remote windows box - very similar results (the connection itself works, just scanning isnt working well) Any suggestions? thanks
