  • 2Power loss during file save operations.
  • 3Corruption of critical label format objects.
  • 4NAND flash block wear.

Solutions

Diagnóstico rápido

If the unit hangs during a print job or refuses to store new labels, memory corruption is likely. Error 0004 alerts you to this system state.

Solución paso a paso

  1. Delete junk files: Use file management tools to purge old temporary formats.
  2. Factory reset: Perform a factory reset to rebuild file partitions.
  3. Reflash firmware: Reinstall firmware using a USB connection to ensure core integrity.
  4. Calibrate: Run a media sensor calibration.

Prevención y mantenimiento

Avoid overloading memory with unused templates. Perform periodic file maintenance to keep the internal partition table clean and efficient.

Cuándo llamar a un técnico

If the board fails to accept firmware re-flashing or consistently throws 0004, the physical NAND chip may have failed permanently.
