I'm on my 2nd Brother laser printer and have never seen a service app to
my knowledge. Just out of curiosity, what is the intended use of the app?

Its called brmainte.exe and it is used to calibrate the laser when
replacing it. Also serial number entry when replacing main PCB. A few other
things.

From the maintenance manual:

Anybody know where brmainte.exe can be found?

Thanks.
