Re: 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.

Brother DPC-165C has 'Init Unable AF' error

Yup. I suspect the head has been removed from the unit. There are adjustments on some printers. It was assembled wrong. The grating noise is likely the auto cleaner. If it cannot go 'home' the unit will not initialize. Possibly the head detect sensor is broken or covered. If the head will not home (moves out and back more than once or slams home hard), 'Init Unable AF'. You may be able to order a service manual from Brother for this. A repair shop can order the manual as well. (I suspect you need a new print head as well. You might want to replace the printer) see tips on bubblejet printers.

Scanner bar will not reset, error "unable to Init. AF"

the problem might be the connection from the mother board of the printer to the scanner maybe due to lost contact and the ribbon was broken you might just have to reconnect it or it might be broken and need replacement

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.

(will post a picture later)

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 ;-)
