How to execute the printer configuration (Self-test) to debug
To print the printer configuration (Self-Test), do the following:
Turn off the printer.
Press and hold the Feed/Pause Button and then turn on the printer.
Release the button when the LED is flashing in amber (5 times).
The LED colour will change in the following order:
Amber (lit) > Red/Amber (blinks 5 times alternately) > Amber (5 times) (Release the button here) > Green/Red (blinks 5 times alternately) > Green (5 times) > Red (5 times) > Green (lit)
The printer calibrates the sensor and detects the label length, prints the internal settings, and then enters the dump mode.
To turn off the dump mode after debugging, please turn the printer off and back on again.
To select the sensor for calibration, send the correct command to the printer:
For the Gap Sensor: the GAP command
For the Black Mark sensor: the BLINE command
You can also print the printer configuration (Self-test) by using the BPM (Brother Printer Management Tool).
