Common causes

  • 1Continuous operation with high heat settings.
  • 2Impaired ventilation near printer intake vents.
  • 3Environmental temperatures exceeding factory specifications.
  • 4Residue buildup increasing head resistance.

Solutions

Diagnóstico rápido

When the Toshiba B-EX4T1 error Head Overheat occurs, the print job pauses immediately to preserve hardware. If you are printing large batches, the heat build-up is normal but needs careful management via your software energy settings.

Solución paso a paso

  1. Stop the print job and allow the printhead 15 minutes to cool.
  2. Adjust your software's 'Heat' or 'Energy' settings downward.
  3. Verify that the printer vents are free from obstructions.
  4. Reset the machine after cooling down to clear the sensor flag.

Prevención y mantenimiento

Use the lowest heat level that achieves good density. Keep the printhead clean; residue increases resistance, which demands more heat. Ensure the printer has at least 10cm of space around all vents.

Cuándo llamar a un técnico

If the error is present after the printer has been off for a long time, the temperature sensor is malfunctioning and likely requires a printhead assembly replacement.
