My brother MFC-3420 all in one has an error 41 caused, I am told by Brother, by me leaving it unused with the ink tanks still in. I have stripped it and cleaned up all the ink from inside it, then flushed it. I cannot clear the error 41 message which means it won't do anything. Anyone got any ideas?
