How to calibrate the Gap/Black Mark Sensor by directly operating the printer
The Gap/Black Mark Sensor sensitivity should be calibrated whenever:
A new printer is purchased
Label stock is changed
Printer initialisation takes place
To calibrate the ribbon and Gap/Black Mark Sensor:
Turn off the printer.
Press and hold the Feed/Pause Button and then turn on the printer.
Release the button when the LED is lit in red/amber (blinks 5 times alternately).
The LED colour will change in the following order:
Amber (lit) > Red/Amber (blinks 5 times alternately) (Release the button here) > Amber (5 times) > Green/Red (blinks 5 times alternately) > Green (5 times) > Red (5 times) > Green (lit)
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 calibrate by using the BPM (Brother Printer Management Tool).
