Common causes

  • 1Adhesive buildup blocking the gap sensor.
  • 2Accumulation of dust/debris on the thermal head.
  • 3Use of poor quality labels that leave chemical residue.

Solutions

Quick Diagnosis

Error err-01 appears when the printer cannot detect the label start or when head temperature is abnormal. Check the LED status indicator.

Step-by-step Solution

  1. Turn off the device and remove the battery.
  2. Open the print mechanism and remove the current label roll.
  3. Clean the printhead using a soft swab dipped in isopropyl alcohol.
  4. Check the gap/black mark sensors to remove any adhesive residue.
  5. Reload the media ensuring correct alignment through the guide sensor.

Prevention and Maintenance

Clean the printhead every 3 rolls. Keep the device away from extreme temperatures to prevent thermal errors.

When to Call a Technician

If the error persists after cleaning and testing with a new media roll, the sensor or internal wiring may be faulty.
