Operating Instructions
1. Basic Scanning
- Point the scanner's window at the barcode you wish to scan.
- Press the trigger button (blue button) to activate the scanning beam.
- Ensure the scanning beam covers the entire barcode. A successful scan is indicated by a beep and the data appearing on your connected device.
2. Scanning Modes
The scanner supports three operational modes:
- Manual Mode: Press the trigger for each scan. Ideal for precise, controlled scanning.
- Continuous Mode: The scanning beam remains active, continuously scanning barcodes without needing to press the trigger each time. Useful for high-volume scanning.
- Automatic Induction Scanning: The scanner automatically detects a barcode within its field of view and scans it without manual trigger activation.
Refer to the included quick setup guide or the manufacturer's website for instructions on how to switch between these modes, typically by scanning specific configuration barcodes.
3. 1D/2D/QR Code Scanning
The OBZ OY-20-US scanner is capable of reading a wide range of 1D and 2D barcodes from both printed labels and digital screens.

4. Scanning Challenging Barcodes
The advanced decoding capability allows for scanning of various challenging barcode conditions:
- Reflective Barcodes: Adjust the scanning angle to minimize glare.
- Distorted Barcodes: Try scanning from different distances and angles.
- Damaged or Blurred Barcodes: The scanner's powerful decoding chip can often read these, but multiple attempts or slight angle adjustments may be necessary.
- Colorful Barcodes: The scanner is designed to handle various color contrasts.

5. Data Editing (Prefix/Suffix)
The scanner supports advanced data editing functions, such as adding custom prefixes or suffixes to scanned data. This feature is configurable by scanning specific setup barcodes found in the comprehensive user guide (not included in this basic manual). This allows for seamless integration with various software systems that require specific data formats.
6. Multi-language Keyboard Support
The scanner supports multiple keyboard layouts, ensuring compatibility with different regional settings. This feature is configurable by scanning specific setup barcodes found in the comprehensive user guide.
Maintenance

- Storage: Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending or twisting the USB cable excessively to prevent internal damage.
- Drop Protection: While designed to be rugged, avoid unnecessary drops or impacts to prolong the scanner's lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | USB cable not properly connected or faulty USB port. | Ensure the USB cable is securely plugged into both the scanner and the host device. Try a different USB port or host device. |
| Scanner does not read barcodes. | Incorrect scanning angle, dirty scanner window, unsupported barcode type, or scanner in an incorrect mode. | Adjust scanning angle and distance. Clean the scanner window. Verify the barcode type is supported. Ensure the scanner is in the correct operating mode (e.g., Manual, Continuous). |
| Scanned data is incorrect or incomplete. | Partially damaged barcode, incorrect data editing settings, or host device input issues. | Try scanning the barcode multiple times from different angles. Check data editing settings (prefixes/suffixes) if configured. Ensure the host device's input method is correctly set. |
| Scanner is slow or unresponsive. | Host device performance issues or excessive background processes. | Restart the host device. Close unnecessary applications. Ensure the USB connection is stable. |
