I was having problems with this too and spent all night yesterday and just figured out this morninig I did not extract/unzip some 'tar archive' files to install package software needed on my pc in order for the scanner to work.
I also have a Brother MFC J430W, so follow these steps brother and it should solve you scanner problem.
step 1 I have gone to the brother site ...http://support.brother.com/g/b/download ... cj430w_all
step 2 I have selected the deb version to download.
step 3 I downloaded 3 files from Printer Driver (a) Driver Install Tool, (b) LPR printer driver (deb package) & (c) CUPSwrapper printer driver (deb package)
then downlaoded 3 files for Scanner Drivers. Note: select 64 bit or 32 bit based on your CPU capablitilites, I have a 64-bit Athlon so i downlaoded
(a) Scanner Drivers Scan-key-tool 64bit (deb package), (b) Scanner Setting file (deb package)
I then downlaoded - ***and maybe someone can confirm, I'm not sure if it is necessary***- PC-FAX Drivers and Source Codes (a) LPR PC-FAX driver
(deb package) (b) CUPS wrapper PC-FAX driver (deb package) (c) CUPS wrapper Printer driver Source Codes (d) CUPS wrapper Printer driver Source
Codes (e) CUPS wrapper PC-FAX driver Source Codes
step 4 I went to Home folder, then Downloads folder then right clicked on - I think they are called Tar Archives, that's what they say in the properties when you
right click and check Properties... anyways,you look for brown icons with a down arrow then I selected Extract Here - which unzips a new package file in
downloads folder- these 3 brown icons (a) linux-brprinter-installer-2.0.0-1.gz, (b) mfcj430wcupswrapper-src-3.0.0-1.tar.gz (c) brmfc-src-1.0.0-1.i386.tar.gz
step 4 I then double clicked on each of the 6 debian packages, the white green mint icons- and installed each one on the drivers on the PC.
step 5 Open Xsane or Simply Scan from the Menu on bottom right corner and select/click Scan to scan item. If you do not haveSimply Scan or Xsane you may seach for it on Synaptic Package and apply/install package on your PC. I had Simply Scan but I I wanted Xsane. I tested both and each one works
