Error and Maintenance LED Indications
As with any sophisticated office product, errors may occur and supply items may have to be replaced. If this happens, your machine identifies the error or required routine maintenance and indicates this with the LEDs on the control panel. The LED indications are explained in this table.
You can correct most errors and perform routine maintenance yourself. If you need more tips, go to your model's FAQs & Troubleshooting page at support.brother.com/faqs.
