STEP A: Verify the Brother machine is powered on and that there are no errors
If your Brother machine's screen (hereinafter called LCD) is blank, the machine may not be powered on. Check the machine to see if it wakes from sleep mode.
If it does not, then make sure it is plugged into a working socket and any power switches are turned ON.
Check the LCD for any error messages. An example would be "Paper Jam" or "Ink/Toner Empty". If the LCD shows an error, troubleshoot the error to clear the issue indicated.
STEP B: Make sure the printer is connected to the computer
If using a USB cable, make sure the cable is connected to both the printer and computer.
Try connecting it directly to the computer and not via a hub.
If using an ethernet cable, make sure the cable is connected to both the printer and router/hub/switch.
Print the network configuration page to check the IP address.
If using a wireless connection, print the network configuration page to check the IP address.
