I solved it. I have a "Johnny come lately" 7 years after the question was asked. There is a cord that I could see, almost paper thin and wide through the scan window. I followed the cord down and had to partially open the side of the printer just enough to fuss with it. I unplugged the cord, straightened out one little bent pin, plugged it back in and viola. It works. Other's problem may be different, but it's worth a try.

I have a Brother MFC 8440. The scan bar has stopped functioning the bar deos not move to scan the documents. It makes intermittant sounds but seems stuck in its resting place?


If the device was moved without the light bar being locked prior to moving, it is possible that the light bar was knocked out of alignment and it will not work. It is very important to lock the light bar prior to moving for that very reason. I would suggest you take the device to a qualified specialist to identify the issue.

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

Sharo al 1631 makes clicing noise and does not


Sounds like your scanner is jammed or the scanner motor has failed.

If you are so inclined, turn the power off, you can remove the glass and try to move the scanner by hand, if you can't move it then it is jammed, if you can move it to the middle and turn the machine back on, does it return it to its home position? if so, the motor may be OK, but the control board may have a problem, if not, the motor have likely failed.

Hope this is of some help.

Hello,
The fastest solution now would be to take a hammer and gently knock the starter (it's the part that makes the click when you turn the key). If you can't reach it with the hammer, use some bar or metal pipe, put one end of the pipe on the starter and knock the other end.
This solution may do the trick if the relay is jammed, and usually helps you to go to the nearest mechanic who should change the bad part.

Brother printer HL2040


Try changing the toner cartridge.
If you are useing refill cartridges and the roller starts to cease
up, the printer still trys to drive it and causes all sorts of problems.The worst thing that can happen is that the drive
gear inside the printer shatters and you will be unable to remove
the drum & toner consumables.

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.
