Common causes

  • 1Print darkness set too high.
  • 2High ambient environmental temperature.
  • 3Excessive work cycles without downtime.
  • 4Obstructed airflow vents.

Solutions

Diagnóstico rápido

Error 004 is displayed on the screen as "Overheat". If the device stops during long print runs of dense graphics, the thermal load has reached its limit.

Solución paso a paso

  1. Cooling: Turn the device off and store in a cool area.
  2. Contrast adjustment: Lower the darkness setting in configurations.
  3. Print speed: Reduce speed to allow for thermal dissipation.
  4. Work intervals: Split large jobs into smaller batches.

Prevención y mantenimiento

Keep the printer away from direct sunlight. Cleaning the printhead is vital, as adhesive accumulation increases friction and heat demand.

Cuándo llamar a un técnico

If the error occurs immediately upon turning the unit on while cold, the printhead temperature sensor is likely faulty.

Ficha técnica del equipo

  • Technology: Thermal Direct.
  • Thermal mgmt: Heat shutdown sensor.
  • Speed: Up to 4.5 ips.
  • Consumibles: High-sensitivity thermal labels.
  • Usage: Intermittent continuous work.

Steps to follow

  1. 1

    Turn off printer

    Power off the unit immediately and let the printhead cool down for 15 minutes.

  2. 2

    Reduce contrast

    If your darkness settings are high, decrease them in the driver settings.

  3. 3

    Ventilation

    Ensure there are no obstructions blocking the printer's air vents.

Frequently asked questions

It indicates that the printhead has reached a temperature above the safe threshold to prevent permanent damage.

Yes, forcing continuous printing can lead to burn-outs on the printhead dots.

High-sensitivity thermal labels allow for lower heat settings, reducing operational temperature.

Take breaks during large print runs and avoid using maximum darkness settings.
