If there is a mechanical malfunction of the Brother Printer device, an Error Code 0b occurs. To fix this error code you need to check that the machine is plugged straight into a wall outlet. You need to unplug everything including the power, phone and communication cable. Now, let the machine sit unplugged for 30 to 60 minutes. Now, plug it again and make sure that it is plugged into a wall outlet and also make sure that it is properly grounded. If this process is not working, then you can obtain Brother Printer Support by sitting at your home.
