A2.2 SETTING ID CODES TO MACHINES
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.)
