The scanner needs to be reset. Turn off the device and then turn it on again.
Please note that when you turn off the MFC's power switch its memory will be cleared. To check whether the MFC has faxes in its memory, click here.

open front cover, press OPTION button, on the LCD will appear a message "NEW DRUM?" ....DO NOT RESPOND....just type on the keyboard "*00" and there will appear a message "Accepted" and use it in your pleasure.
PS. in any case i blocked with paper labels the viewing windows from transparent plastic on the toner itself....
Mr. Brother, do not try to be smarter than your customer

I have the answer. I just fixed mine. The sensor is not really on the door. You have to remove the door by openning it all the way and carefully sliding it out ( one of the pegs holding the door is hourglass shaped. This will slide out first. The other is round. You will see a black flap that covers a red drum. Pull the flap down carefully. There will be a six inch long rod it's about 1/8 of an inch in diameter. It extends from the middle of the flap all the way to the right side. This probably popped out of place. Make sure that it is all the way to the right as this is where the sensor is. There is a little spring on the bar on the left side. This should be straight up and down. if it is not, then you need to fiddle with the bar.
The trick was that the sensor is NOT on the door, but on this inner flap. When the door closes it pushes this flap agains the drum and the little bar activates the sensor.
Please do not applaud so loud, you are ambarrazing me!!! hehehe. Good luck!.
