brother printer firmware update password reset
I spent many hours doing a variety of factory resets and trying the password above, "access". Apparently, Brother pushed out a firmware update recently which changed the default password on many devices to "initpass". So, if you are locked out of the web interface give this a try.

It looks like you might be able to reset to factory settings via the control panel on the device as well.
From Brother's FAQ:
Via the control panel (only for network ready models)
- Make sure the machine is not operating, then disconnect all the cables from the machine (except power cable).
- Press the Menu or Menu/Set key on the control panel.
- Press up or down navigation key to select LAN or Network and press Set, Menu/Set or OK.
- Press up or down navigation key to select Factory Reset or Network Reset and press Set, Menu/Set or OK.
- Select Reset.
- Select Yes.
- The machine will re-start, re-connect cables once this is complete.
