Brother's scanner is not working on Ubuntu 12.10 32-bits

I have a brother DCP J125

I have downloaded and installed the scanner driver but Simple Scan shows that it couldn't detect any scanner.

I'm running on Ubuntu 12.10 32bits, the steps show in the Brother FAQ do not work for me as I can't find the lib64 folder.

Can anyone help me?
