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.
