At least in the log you sent me it fails in gl646_search_start_position, trying to read the last 64 bytes of a scan. I am not aware of any changes affecting that function. > - lineart mode is broken . I could change read_ordered_data to convert gray data to lineart. But the changes to make the scanner output lineart are small: Set lineart bit, modify read_bytes_left and words_per_line to correctly take lineart into account(which would be setting depth correctly). At least that did the trick for my scanner. I cannot test on a gl646, so i am just attaching my idea of the changes needed. Please test. > - after a few scan, especially when changing dpi, I get 'color noise' > instead > of pictures. Restarting the scanning program fix it. Sounds like memory corruption.

I will now contact to Brother and probably I will use my printer/scanner for printing only with Linux. I still have xp on other machines so I can still scan, no problem. If I find any news, I will let you know. If you hear nothing from me, then they just dont support Linux for this scanner yet. Again, thank you.

Sometimes it helps to link the sane.d directory to /etc: ln -s /usr/local/etc/sane.d /etc/sane.d Regards, Ulrich Deiters
