How can I troubleshoot a Brother printer that is in an error state?

To troubleshoot an 'Error State' on your Brother printer, start with the basics. Power cycle the printer by unplugging it for at least 60 seconds, then plugging it back in. Check for any paper jams, ensure all covers are closed properly, and verify that the ink or toner cartridges are correctly installed. Also, restart your computer and re-establish the printer connection.
