Also I believe there was an update to DBUS the other day -- have you
installed the Ubuntu updates in the past week? You may have run into a
bug in the DBUS rules -- someone may have accidentally identified the
Brother MFC scanner as an HP printer or something like that.

Which version of Ubuntu are you running?

I haven't found a DBUS troubleshooting page, but it might be helpful
to see in more detail what it's doing when it sees your
scanner/printer.
