The ERR-002 is a common calibration error. If the status light flashes red, check if your labels are skewed. Also, inspect the sensor area for dust or paper adhesive that might be masking the reader.

Solución paso a paso

  1. Open the label compartment.
  2. Remove the roll and check for stuck labels or debris on the sensor path.
  3. Clean the sensor using compressed air or a swab dipped in isopropyl alcohol.
  4. Reinsert the media roll, ensuring it's straight.
  5. Close the cover; the printer should trigger an automatic sensor calibration.
