Great video!

When trying to calibrate using these steps I get an error stating "Write Tag Failed" after the calibration process that starts at 6:40. Any idea what is causing this issue?

Do you know if the tags have been locked by a previous supplier? This would prevent the printer from being able to write to the tags.
