The scanner head can be tilted up to 15 degrees to find the optimal scanning angle.
3.2 Scanning Modes
The Tera 9100 supports two primary scanning modes:
- Continuous Scan Mode: The scanner continuously emits a scanning light, ideal for high-volume environments where items are passed quickly over the scanner.
- Sensor-activated Mode: The scanner activates its light only when a barcode is detected in its scanning field, conserving energy and reducing light emission when not in use.

5. Troubleshooting
If you encounter issues with your Tera 9100 scanner, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | USB cable not properly connected or faulty USB port. | Ensure the USB cable is securely connected to both the scanner and the computer. Try a different USB port or computer. |
| Scanner does not read barcodes. | Incorrect scanning mode, dirty scanning window, or unsupported barcode type. | Check if the scanner is in the correct mode (Continuous or Sensor-activated). Clean the scanning window. Verify the barcode type is supported by the scanner. Ensure proper distance and angle. |
| Scanned data is incorrect or incomplete. | Barcode damage, incorrect data formatting settings. | Try scanning a different, undamaged barcode. Review the customizable scan mode settings (prefix/suffix, character dropping) in the programming guide. |
| Scanner beeps but no data is transmitted. | Software or application issue on the host computer. | Ensure the cursor is in a text field where data can be input. Test with a simple text editor (e.g., Notepad) to confirm basic functionality. |
