Toshiba TEC B-SX5T error E-15: Media Detection Failure

The Toshiba TEC B-SX5T error E-15 signifies that the sensor is failing to identify the label gap. This usually stems from dust accumulation, improper sensor type selection, or media calibration drift after changing label stock.

Common causes

  • 1Dust on the optical sensor.
  • 2Incompatible media settings.
  • 3Poor label roll alignment.
  • 4Calibration failure following stock changes.

Solutions

Diagnóstico rápido

If the printer fails to stop at the start of the label, the E-15 error is triggered. Verify if the printer is set to the correct sensor type for your label type (gap vs. black mark).

Solución paso a paso

  1. Check proper material path through sensors.
  2. Clean the lens with a soft, lint-free cloth.
  3. Perform an auto-calibration through the control panel.
  4. Fine-tune sensitivity settings if necessary.

Prevención y mantenimiento

Monthly sensor and printhead cleaning is critical. Using certified label stock significantly reduces the chance of adhesive debris fouling the sensor.

Cuándo llamar a un técnico

If recurring calibration fails, the sensor hardware may be faulty and need replacement to restore reliable media tracking.

Steps to follow

  1. 1

    Adjust guides

    Center the media roll and ensure side guides hold the material securely without bending.

  2. 2

    Sensor calibration

    Access the menu and run 'Sensor Calibration' to allow the printer to re-map label gaps.

  3. 3

    Physical check

    Use compressed air or a soft brush to clean the transmission/reflective sensor of dust buildup.

Frequently asked questions

Error E-15 means the printer cannot detect the gap or black mark, leading to media running through without stopping.

Yes, transparent labels require manual adjustment of sensor threshold levels in the printer menu.

Yes, cleaning the optics after every roll is best practice to ensure reliable detection.

Using the official Toshiba TEC drivers ensures better communication and sensor positioning commands.
