What to Do If a Reflective Mark Sensor Tracks Inaccurately

Reflective mark sensors determine color by emitting and receiving light. When tracking is inaccurate, consider the following causes and fixes.

Causes

1. Ambient light changes interfering with the sensor.

2. Poor mark contrast due to dirt or wear.

3. Insufficient calibration.

4. Incorrect installation distance or angle.

Solutions

1. Optimize lighting or use shading.

2. Maintain and replace marks as needed.

3. Implement thorough calibration procedures and recalibrate after environmental changes.

4. Adjust installation position and angle to ensure proper signal strength and view.

Applying these measures improves tracking performance and ensures reliable operation of automated systems.
