6. SYSTEM MODE
6.1 Feed Gap Sensor / Black Mark Sensor Adjustments
Each type of media roll has its own label separators, such as gaps, holes, notches or black marks. Those
separators need to be detected by media sensors, so the label can be printed in correct position. B-FV4
provides transmissive and reflective sensor calibration for media detection.
1. Turn off the printer, make sure the media is correctly loaded, and close the top cover.
NOTE:
Do not place a pre-printed area above the media sensor, as doing so disables correct sensor
calibration.
2. Press and hold the [FEED] button while turning on the printer.
3. Both status lights (LED 1 and LED 2) will light up in the following order:
Orange Green Other colour sequences
4. Release the [FEED] button when LED 1 and LED 2 light to match the sensor you want to calibrate.
Feed Gap (Transmissive) Sensor: LED 1 green, LED 2 red
Black Mark (Reflective) Sensor: LED 1 green, LED 2 orange
5. Press the [FEED] button. The printer will feed the media and perform the sensor calibration.
