6. Troubleshooting
6.1 "Please Remove Label" Message
If the scale displays the message "Please Remove Label", this typically indicates one of two issues:
- The label size currently loaded does not match the configured label size in the scale's settings.
- The Label Peel Sensor value has changed or is obstructed.
Resolution:
- Verify that the correct label size is loaded and that it matches the settings programmed into the scale. Adjust settings via the XDB Manager software if necessary.
- Inspect the Label Peel Sensor area for any obstructions or debris. Gently clean the sensor if it appears dirty.
- If the issue persists, it may require recalibration of the sensor or a software adjustment. VisionTechShop provides instructional videos on their website or YouTube channel for resolving this specific issue. Contact technical support for further assistance.
6.2 Scale Not Powering On
Ensure the power adapter is securely connected to both the scale and a working power outlet. Check the power outlet with another device to confirm it is supplying power. If using a power strip, ensure it is switched on.
6.3 Inaccurate Weight Readings
Ensure the scale is placed on a level, stable surface, free from vibrations or drafts. Verify that nothing is touching the weighing pan or the scale's base. If inaccuracies persist, the scale may require recalibration by a qualified technician.
