How to Fix Offline or Paused Errors in Brother Printers?

First, turn on the machine and wait for a few seconds until the LCD screen flashes.
If the screen is blank, then maybe the printer is not powered on or the disconnected.
Check the power outlet, see if it is waking from sleep or not.
If you notice any error on LCD, for instance, ‘Paper Jam’, ‘Offline’ or ‘Paused’ then the problem is likely with the connection cable. In that case, replace it.
Or try to clean it; sometimes some dust particles may also create errors.
