To solve this issue, try one of the following suggestions:

• Make sure smart labels with RFID tags are located in the correct position.
• The RFID tag could be defective. Try another tag.

  Always test RFID media on your printer before purchasing large quantities of media.

• Set the label size correctly. Then calibrate the RFID tag.
• Set the sensor sensitivity correctly (Sensor > Gap/Bline Ref Rate).
• Check the data length size of the RFID commands.
