Toshiba TEC B-EX6T3-GS Pro Error ERR-R03: Label Sensor
The Toshiba TEC B-EX6T3-GS Pro error ERR-R03 occurs when the printer fails to detect the gap between labels. Without this signal, the machine cannot align the print content properly, causing the printer to pause for security. Calibration is the primary solution for this fault.

Common causes
- 1Adhesive or dust residue on sensor.
- 2Improperly loaded media.
- 3Incompatible media type.
- 4Loss of gap sensor calibration.
Solutions
Diagnóstico rápido
If the printer continuously feeds paper or stops after one label, the gap sensor is failing to detect the label edge.Solución paso a paso
- Check if the labels are aligned with the center guide.
- Wipe the sensor path clean.
- Run a media calibration from the menu.
- Adjust sensitivity if using specialty media.
Prevención y mantenimiento
Clean the sensor during every roll change. Use high-quality labels to prevent adhesive residue from interfering with sensor optics.Cuándo llamar a un técnico
