Note • This error message varies by reader type.
No RFID tag was detected in the RF field. Several things can
cause this error:
• No acceptable RFID tag is in the RF field. This can happen if an
RFID label is present but the transponder is not placed correctly
within the label or if the wrong tag type is used.
• The read/write power being used is too low.
• The RFID tag is weak or dead.
Retry with another RFID tag. Make sure you have the right tag
type selected and that you are using a tag that is supported by your
printer. If the problem persists, contact Technical Support.
