If the message is 'Unable to Clean: Error 46' I would recommend checking out this video. If however you are receiving 'Error 4F' this is a mechanical issue and I would advise getting in touch with a printer technician or Brother themselves.
Downloaded service & repair manual for brother mfc 5840CW- my unit. Will follow repair directions to check the memory then replace required parts. Will be cheaper and faster than finding a repair shop and paying as much as the macine to fix it! Rip off prices for repairs today on units so they can get you to leave them and buy a new one. Then they fix the unit and sell it "refurbished"- not mine!
Your information on clearing memory, the ink cleaning codes and taping the cartridge from over cleaning was good. Thanks for the help!
I saw on this site codes for another MFC to clear memory and reset the cleaning unit count code to zero. It worked on two of my brother mfc 820cw units. The third mfc 5840cn had unable to print error message 46- nothing at Brother. they want you to take everything to a repair shop.they don't help at all. Then the error went to 4F when I tried toclear the memory.As Iunderstand that message- it means I have to replace the printer head. Have no clue where or what it is. But I can read a manual as well as anyone and follow directions to fix it! Can't be worse than it is now! Good luck
