Error and maintenance messages

B

As with any sophisticated office product, errors may occur and consumable items may need 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 
below.

You can correct most errors and routine maintenance by yourself. If you need more help, the 
Brother Solutions Center offers the latest FAQs and troubleshooting tips.
