Sometimes automatic calibration doesn’t always work with desktop printers.

While the Bixolon SLP-DX420 comes with Smart Detection Mode, a feature meant to automatically calibrate when you press the Feed Button, you may need to calibrate the printer yourself.

There’s separate instructions for calibrating labels with gap sensors and labels with black timing marks. Make sure you are using the correct one!

Below are the instructions for calibrating a Bixolon SLP-DX420:

Gap Sensor Calibration

  1. Press and hold the Pause button for 2 Seconds
  2. Press the Feed button when LED 1 is orange and LED 2 blinks green 4 times

Black Timing Mark

  1. Press and hold the Pause button for 2 Seconds
  2. Press the Feed button when LED 1 is orange and LED 2 blinks orange 4 times
