Common causes

  • 1Optical sensor blocked by paper dust.
  • 2Incompatible label material.
  • 3Lost factory calibration after a firmware update.
  • 4Natural degradation of the sensor LED emitter.

Solutions

Quick Diagnosis

Error ERR-02 appears if the optical sensor path is blocked or if the material isn't registering. If the printer attempts to feed but halts immediately, focus on the sensor area.

Step-by-Step Solution

  1. Switch off and open the printer compartment.
  2. Remove labels to access the sensor slot.
  3. Clean the sensor path with compressed air or a dry cloth.
  4. Reload labels correctly through the guides.
  5. Run the auto-calibration feature from the dashboard.

Prevention and Maintenance

Clean sensors monthly to prevent paper debris interference. Always use certified labels to ensure correct transparency values for the sensors.

When to Call a Technician

If label detection fails post-calibration, the internal optical module may be failing and requires replacement.
