SOURCE: Brother mfc 8500 clicking noises
If you open the cover and remove the toner/drum unit, you will see (on the left side as you remove) a small hole with two triangle teeth.
on either side of this hole are two small phillips head screws. this is the problem we had with our clicking noise. As the machine tries to turn the toner/drum, the innards of the toner are becoming harder to turn. So the part of the fax machine that fits in the hole end up stripping the teeth in that hole. If you have an old toner cartridge, you can remove the gearing from it (where the small phillips head screws are) and use it to replace the gearing on the newer cartridge. Or go buy a new toner cartridge.

if the message refers to the scanner, open the cover of the feeding unit on top of the printer and clean it with compressed air. Most probably an insect got stuck somewhere

press the 3 and 9 button at the same time in ready mode.
then the reset menu will appear, press the up or down arrow until you get to drum.
and select 1 to reset or 2 to exit.
it will return the ready state and your done.
