Hello. I am using Sane from Debian Etch 1.0.14-2. I have installed the drivers from Brother itself and they work after fixing the permissions with this lines in /etc/udev/libsane.rules: # Brother MFC 7420 SYSFS{idVendor}=="04f9", SYSFS{idProduct}=="0180", MODE="664", GROUP=" scanner" Hope this helps. Thank you and goodbye!
