I recently had this problem - tested fuser and all sensors.
The fix is to reset the memory.
To do this, enter the Maintenance mode. Menu, * 2864
(enter the number quickly)
then type 01 ( zero one ), this will reset all memory including the user settings.
Finally type 99 to exit Maintenance mode.
The printer will restart and the error will be gone. Test out with copy and printer reports
Hoping this fixes your problem

SOURCE: Replacing Brother MFC-8440 Fuser
To remove the fuser - remove the tray at the bottom and the back tray (4 screws, 2 either side) lift out the phone line box on the right (looking from the back - 2 screws) and swing it out of the way (careful as cable isn't too long) 2 screws either side of the fuser (long black object at the bottom) unplug the halogen lamp (white plug on left) and small 5 wire plug on right, and lift out fuser unit.

If the black lines comes when using the ADF (top feeder), try to see if you get the same problem when using the scanner glass or receiving faxes. If you don't, you simply have to clean the glass strip to the left of the a4 sized scanner glass. Wipe it with a dry cloth piece, no paper and no water/alcohol. If you see some dirt there that you're unable to simply wipe off, try to use a cotton wool to "rub" it off.
