Ubuntu :: Brother Inkjet Printer & Scanner Failed

I have a Brother MFC-240C inkjet printer & scanner. On installation of Maverick Meerkat v. 10.10, my scanner function failed. I added the same line into the file as for Lucid Lynx v. 10.04 and the scanner has scanned perfectly. The lines Brother gives are for the following file: Ubuntu 9.10, 10.04

1. Open "/lib/udev/rules.d/40-libsane.rules" file.
2. Add the following two lines to the end of the device list. (Before the line "# The following rule will disable ..."):

# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"
