You simply have to reconnect the flat cable of the scanner to the main pcb.
Therefore you have to open the mfc by opening the scanner cover as when you have a paperjam. Loose the the blue support by pressing down the clip on the right side and pushing the support to the right.
Disassemble the "Z"-forming by carefully pressing it up at the latches which can be seen. The flat cable has to be connected to the main pcb simply by sticking it into position :-)

Error will disappear.

Unable to Init AF - New printer!

sure (this advice costs you some greetings from me to the beloved bahamas ;-))

you have to open the scanner as you have done to connect the usb cable. When opened you can see a "z" like small cover going from panel to the right rear side.
Open this cover which hides the flat cable of the scanner. The cable needs reconnecting to the main board. Simply stick it carefully into the right positon.

You have to reconnect the scannerflatcable to the main circuit board.

Open the scanner top as when a paperjam had occured. Remove the "Z" lookinglike plastic cover near the middle running to the right side which hides the flatcable. Simply stick the flatcable into the mainboard, close the cover 
again and close the scanner top.

Brother MFC-240C init. unable AF error message

Sure. No prob.

Open scanner cover as you would do to check for a paper jammed sheet.

Do open the plastic which runs from middle to the right side (looks like a "Z" turned clockwise). Use a small screw diver for that. beneath you will find th flat cable of the scanner. You have to reconnect the flat cable by simply sticking it into position onto the main circuit board. make sure flat cable is in good position and click the" Z  "onto the channel. Close cover then power up and do what ever you want to do with your mfc ;-)

Init unable AF

AF means that the CIS scanner is (can) not (get)in right position. This could be because of a broken scanner flat cable, or a loose flatcable or a defective pcb. Check flatcable connection at the pcb (Open scanner like changing carts, open flatcable cover with a screwdriver. Does the flatcable stick in the pcb? (There is only the flatcable without a connector ;-)) Reconnect and power up mfc again. If it doesn't help please write again here.
