Toshiba B-SA4TM III Error print-head-temp: Solution

The Toshiba B-SA4TM III error print-head-temp is a critical safety warning indicating the thermal print head has exceeded safe temperature limits. If ignored, the head can suffer permanent damage to its resistive elements. This error is usually triggered by an excessively high printing temperature setting or long print cycles.

Common causes

  • 1Temperature (Heat) settings too high.
  • 2Dirt buildup on the print head surface.
  • 3Insufficient ventilation of the workspace.
  • 4Ribbon not suited for the material.

Solutions

Diagnóstico rápido

If this error appears after continuous printing, the head is simply thermally exhausted. If it happens immediately upon startup, the temperature sensor might have a circuit fault.

Solución paso a paso

  1. Stop printing and keep the cover open to speed up ventilation.
  2. Adjust software to reduce the 'heat' or 'darkness' level.
  3. Clean the head with a soft cloth and isopropyl alcohol, as accumulated dirt forces the head to work harder.
  4. Check speed, as reducing it can help dissipate generated heat better.

Prevención y mantenimiento

Use original ribbons compatible with the label material. Poor quality material requires much more heat to transfer the image, which wears out sensors and raises temperature. Perform regular cleaning with every roll change.

Cuándo llamar a un técnico

If the error appears immediately upon turning on the machine without having printed a single label, the temperature sensor on the print head is likely defective and requires replacement.
