Error Cause; Error Indication - Brother DCP-7030 Service Manual

2.

ERROR CAUSE

This machine includes a self-diagnosis function. If the machine does not work normally it
judges that an error has occurred (For example: Print Unable 6A), and indicates the
corresponding error message on the LCD, which in turn helps the end user to quickly identify
the problem.
The error code is possible to display by the
Code Indication (Function code 82)" in Chapter 5).
