Common causes

  • 1Loose printhead data cable.
  • 2Sensor blockage due to dust or label debris.
  • 3Mainboard failure affecting thermal sensing.
  • 4Mechanical vibration causing cable fatigue.

Solutions

Quick Diagnosis

The error 105 appears at boot-up. If the sensor is offline, the firmware halts operations to protect the printhead from overheating or damage.

Troubleshooting Steps

  1. Power off the printer.
  2. Inspect the ribbon mechanism and thermal printhead area.
  3. Ensure the flat ribbon cable is clean and seated perfectly in its port.
  4. Perform a cold reboot and check if the error is cleared.

Maintenance and Prevention

Regularly clean the printhead using isopropyl alcohol and lint-free swabs. Keep the printing environment free from heavy dust and extreme temperature fluctuations.

When to call technical support

If the cable is properly connected and the error code remains active, the printhead assembly may require professional replacement.
