I have Brother MFC-J430W for years and when the Black ink ran out, I bought a new one.. Unfortunately, after several "Cleaning" (using Menu>Ink>Cleaning), it still print blank for the black ink. I tried to wipe the interior of the ink cartridge (holder) with baby wipes, and after the test print.. it worked!!!! Maybe the ink dried out, i'm not sure.. but I'm happy that I can now print using the black ink. :)
