I am using the control panel to manually set the IP address of the Brother machine. When I submit the settings and select the "Factory Reset" option to activate the settings, the Brother machine resets itself as normal. But when I print a configuration page, I see that the Brother machine is not using the IP address I entered. Instead it's using a DHCP based address or an APIPA based address. Why is this happening?

By default the the Brother machine is configured to work in AUTO mode. If you manually specify an IP address, it will still be set to AUTO mode.
Because of this, when the Brother machine resets itself, it still uses this AUTO setting and will ignore your manually assigned IP address. If you wish to manually configure an IP address, you must also change the "IP Config" method to "Static". This will force the Brother machine to work in Static mode.
