ERROR 41 ON BROTHER mfc

How do you change the printerhead of a Brother MFC3100C when it does not respond to the "Ink button' procedure to bring the cartridges forward for access?

This is definitely the print head. You will need to purchase a new print head and install this. It is very easy to install all that you need to do is lift the printer lid and extract the ink cartridges. The printhead is the black part under the ink cartridges and on either side of it is a lock and release bar. push these down and out wards to loosen them and then lift the print head out. replace the print head and then you will need to input the print head ID in maintenance mode on the printer. Turn the printer off and hold down the menu/set button and power on. You will here it beep and all the lights flash on the panel. The punch in 68 2580 I think from memory i could be wrong but just look it up if you can get hold of a service many and then enter the new printhead code and 99 to exit. Done Hope this answers your question.
