Error Codes; Error Indication - Brother DCP-8085DN Service Manual

3. 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.
