4.3.2 Gap/Black Mark Sensor Calibration, Self-Test, and Entering Dump Mode During the calibration of the Gap/Black Mark Sensor, the printer will detect the label length, print the internal configuration (self-test), and then enter the dump mode. Calibrate the Gap or Black Mark Sensor if the sensor's settings used in the last print job are not suitable for the current print job. To calibrate the Gap/Black Mark Sensor: 1. Turn off the printer. 2. Press and hold the Feed/Pause Button, and then turn on the printer. 3. Release the button when the LED is flashing in amber. Note The LED color will change as follows: Amber  red (5 times)  amber (5 times)  green (5 times)  green/amber (5 times)  red/amber (5 times)  green (lit) 4. The printer calibrates the sensor and detects the label length, prints the internal settings, and then enters the dump mode. Note To select the sensor for calibration, send the correct command to the printer:  For the Gap Sensor: send the GAP command  For the Black Mark Sensor: send the BLINE command For more information about the available commands, see the FBPL Command Reference Manual. 27
