  • 2Incorrect media width settings.
  • 3Poor media guide positioning.

Solutions

Diagnóstico rápido

If the printer displays ERR-04, check the label path. If labels are loaded correctly, the sensor might have residue, preventing it from distinguishing between the label and the backing.

Solución paso a paso

  1. Lift the printer cover and remove the media.
  2. Gently clean the sensor area with 99% isopropyl alcohol.
  3. Reload the label roll and feed it under the guides.
  4. Perform the auto-calibration cycle.

Prevención y mantenimiento

Maintain a clean print environment. Avoid cheap labels that leave excessive adhesive residue on the platen or sensor.

Cuándo llamar a un técnico

If the sensor fails to calibrate after a thorough cleaning, the internal sensor board may be faulty.
