Error Indications - Brother HL-2290 Service Manual

3. ERROR INDICATIONS

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 service personnel to quickly find out the problem.
3.1 Error Codes
The shaded errors hardly occur under normal use. They may be caused by noise around the
installation site, variation in power supply voltage, or software failure.
