Brother MFC-3420 error 41?

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?

Go to www.bopparts.com and look for part # LK0935001. By changing this part (Printhead) you will take care of the problem. It is only $39.99 and is very simple to change. No tools or skill needed and instructions are included.

You will find your answers here. It would appear that many brother printers are having this problem and more. Good Luck!
