Common causes

  • 1Defective RFID tag.
  • 2Incompatible chip protocols.
  • 3Antenna range mismatch.
  • 4External electromagnetic interference.

Solutions

Diagnóstico rápido

Error 004 indicates that the printer's RFID reader could not handshake with the tag. This often happens if the tag is not recognized or the chip position is outside the writing range of the internal antenna.

Solución paso a paso

  1. Verify that you are using Gen2 compliant RFID labels.
  2. Check the chip orientation to ensure it aligns with the reader.
  3. Consult the ZT411R configuration menu for RFID antenna power settings.
  4. Replace the media roll and try a fresh set of tags.

Prevención y mantenimiento

To avoid RFID encoding errors, ensure that your environment is free from high RF noise. Use qualified RFID media and keep the printer's internal antenna area clean.

Cuándo llamar a un técnico

If you see this error for every label printed, your internal RFID antenna may require professional calibration or replacement.
