Common causes

  • 1Excessive darkness settings for the used ribbon.
  • 2Operating environment with very high ambient temperatures.
  • 3Obstructed ventilation at the rear of the device.
  • 4Wear of the internal printhead thermal sensor.

Solutions

Quick Diagnosis

If the unit halts after intensive printing, the head exceeded its thermal limit. This is typical in high-speed environments or if darkness levels are too high.

Step-by-step Solution

  1. Turn off the unit and disconnect from power.
  2. Verify the site has proper ventilation.
  3. Reduce 'Darkness' levels in your design software.
  4. If the error remains, allow the head to cool down for an extended period.

Prevention and Maintenance

Clean the printhead with alcohol regularly. Do not exceed recommended print speeds and adjust darkness according to ribbon type to avoid unnecessary heat.

When to call a technician

If the error appears immediately after turning on the unit without prior printing, the printhead temperature sensor is likely defective.

Steps to follow

  1. 1

    Cool down equipment

    Turn off the printer and let the printhead cool down for at least 15 minutes.

  2. 2

    Reduce darkness

    Adjust the 'Darkness' value in settings to lower the heat output.

  3. 3

    Improve ventilation

    Ensure the printer is not close to heat sources or obstructed walls.

Frequently asked questions

The thermal sensor detects that the printhead has exceeded the safe operating threshold to prevent electrical damage.

Yes, ignoring it can lead to permanent burning of the thermal elements in the printhead.

Low-quality ribbons might require more heat to transfer, increasing the risk of this error.

Use the minimum speed and darkness settings required for clear print quality.
