Brother maintenance apps?
 

The service manual for Brother HL-22xx (2240, 2250, 2270, etc.) says there is
a “maintenance device driver” (which, from documentation I’ve seen,
seems to be an app) for windows.
I’ve searched the ‘net but can’t find this--or other--service apps for
Brother.

Any pointers to any Brother service apps would be greatly appreciated.

Thanks.
