Error and Maintenance Messages
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 shows the appropriate message. The most common error and maintenance messages are shown in the table.
Follow the instructions in the Action column to solve the error and remove the message.
You can correct most errors and perform routine maintenance by yourself. If you need more tips: Visit support.brother.com, and click the FAQs & Troubleshooting page.
