Brother MFC-290C not printing black ? (or any other color for that matter)
REAL Solution (If the 'cleaning' option didn't work)
1. Get one of those COMPRESSED AIR CANS.
2. Remove all cartridges.
3. hold the air can nozzle tight to where the ink is drawn from.
4. blast away (Some spray-back is expected so hold some tissue or something over everything so that you don't get ink dots all over your face.
That's the only thing that worked for me.
