Error Indications - Brother HL-L2300D 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
Errors in shaded column do not usually occur during normal use. The possible causes are
noise around the installation site, fluctuation of the power supply voltage, and failures in the
software.

After the heat unit was heated normally, the
0504 center thermistor of the fuser unit detected a
temperature lower than the specified value.
The center thermistor of the fuser unit
detected a temperature rise greater
0505
than the specified value within the
specified time.
The center thermistor of the fuser unit
0506 detected a temperature fall greater than the
specified value within the specified time.
The hardware detected a temperature
050A error through the center thermistor or
the side thermistor of the fuser unit.
When the center thermistor of the fuser unit
was lower than the idle temperature, the side
050B
thermistor detected a temperature higher
than the specified temperature.
When the center thermistor of the fuser unit
was higher than the idle temperature, the
050C
side thermistor detected a temperature lower
than the specified temperature.
050D ―
050F An error occurred in the fuser unit.
A communication error occurred
0600 between the ASIC controlled by
engine and the motor driver.
0700 ―
0800 ―
Detected irregular power supply for
0900
more than 100 times.
0A01 ―
0A02 Detected a fan failure.
An error occurred in the high-voltage
0B01
power supply PCB ASSY while operating.
An error occurred in the high-voltage
0B02 power supply PCB ASSY when the
machine was in the ready state.
