Honeywell PX940V error 1004: RFID Encoding Fix

Honeywell PX940V error 1004 occurs when the internal RFID reader fails to encode a tag successfully. This status usually triggers a stop in the print queue to prevent wasting labels. Often, simply checking the media alignment resolves the issue, but configuration adjustments are occasionally required.

Common causes

  • 1Inlay misplacement relative to the antenna.
  • 2Write power level set below threshold.
  • 3Incompatible RFID tag protocol.
  • 4Adhesive residue buildup on the sensor path.

Solutions

Diagnóstico rápido

Error 1004 appears on the UI screen when the antenna detects an invalid inlay or lack of signal. Verify if the material is correctly loaded. If you see the message immediately after sending a job, the tag might be misaligned.

Solución paso a paso

  1. Open the printer housing and inspect the label path for alignment.
  2. Navigate to 'Settings' > 'RFID' > 'Antenna Test' to check detection.
  3. Increase 'Write Power' in the menu if the printer fails to encode consistently.
  4. Perform a media calibration to ensure the sensor detects the gaps accurately.

Prevención y mantenimiento

Clean the sensors with compressed air weekly. Ensure media is stored in a dry, room-temperature environment to prevent adhesive bleeding. Always use genuine ribbons to ensure high print quality.

Cuándo llamar a un técnico

If you have performed a factory reset and verified media compatibility without success, the RFID reader hardware might be failing, requiring professional technical support.

    Access RFID settings to calibrate write power levels.

Frequently asked questions

The error 1004 indicates that the RFID antenna cannot detect the tag or the signal strength is inadequate for encoding.

It is a process error that stops the printing cycle but does not cause permanent hardware damage if addressed early.

Always use certified RFID tags compatible with your specific printer's frequency (UHF/HF).

Clean the printhead and rollers every 50,000 labels to ensure optimal performance.
