Brother MFC-9840CDW, DCP-9045CDN 2.ERROR CODES, 2.1Error Indication

2.ERROR CODES

This machine includes a self-diagnosis function. If the machine does not work normally it judges that an error has occurred, and indicates the corresponding error message on the LCD, which in turn helps the end user to quickly find out the problem.

2.1Error Indication

The error codes shaded in the table below are recoverable errors if following the User Check items.
