This looks like the other mail here with subject "Sane problem with Brother MFC J6710DW scanner.", see http://lists.alioth.debian.org/pipermail/sane-devel/2013-December/031906.html that reads in particular: ---------------------------------------------------------------- ... Brother MFC-J6710DW USB scanner ... Starting xsane from the command. It starts, the GUI, header says: "xsane 0.998 MFC-J6710DW scanner" The error pops up: "Failed to start scanner: Invalid argument" ---------------------------------------------------------------- The Brother MFC-420CN is at least listed at http://www.sane-project.org/cgi-bin/driver.pl?manu=Brother&model=&bus=usb&v=&p= for the "brother2" driver/backend but with status "untested". The "brother2" driver is an external backend for SANE, see http://www.sane-project.org/lists/sane-backends-external.html An external backend for SANE usually means that there is no free source code available so that nobody except those who made that driver can usually help to debug issues with such a driver. Perhaps there is documentation how to get debug messages for the "brother2" driver so that you could at least try to find out what the root cause could be here. >From my current point of view I don't think there is an issue in XSane or in SANE because otherwise there should have been more such reports and not only for drivers from Brother. >From my current point of view it looks more like an issue in the drivers from Brother. I think you should get in contact with Brother because they can find out what the root cause is.
