Brother 4F is this have a go it could work for you.
Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.
This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.
All I ask is please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
