Brother driver machines are assigned unique ID codes (character strings) at the factory. If you
replace the main PCB of the machine, the machine will lose its assigned ID code so that it will
not be identified by the connected PC*.
You need to assign a unique ID code (character string) to the machine according to the
procedure given here. For models covered by this manual, set serial numbers given to
individual machines as ID codes.
(*ID codes are essential when more than one machine is connected to a single PC via USB.)
