6. Operating Instructions

1. Positioning: Place the item with the barcode within the scanner's field of view, typically 3-30cm from the scan window.
2. Automatic Scanning (Self-Sense): The T-D7 features a self-sensing capability. When a barcode enters its scanning area, the scanner will automatically activate its light source and attempt to read the barcode.
3. Successful Scan Indication: Upon a successful scan, the scanner will emit a buzzer prompt, and the barcode data will be transmitted to your connected device.
4. Scanning from Screens: The scanner is capable of reading barcodes displayed on digital screens, such as mobile phones or tablets. Ensure the screen brightness is adequate for optimal scanning performance.

7. Maintenance

• Cleaning: Regularly clean the scan window with a soft, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Do not use harsh chemicals or abrasive materials.
• 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 damage.

8. Troubleshooting

Q: Why can some barcodes not be read?

• This product supports all common 1D and 2D barcodes. Some less common or unused barcode types may require specific activation settings.
• Heavily damaged, obscured, or poorly printed barcodes may be unreadable.
• Ensure the barcode is within the optimal scanning distance (3-30cm) and properly aligned with the scan window.
• If issues persist, please contact technical support for assistance.

Q: Can I add or remove line feed and other features?

• Yes, the scanner supports commonly used barcode features such as line feed, backtracking, and storage mode.
• For specific customizations regarding functionality or appearance, please contact TEKLEAD technical support.

Q: What should I do if unreadable characters appear after scanning?

• This usually indicates a mismatch between the barcode scanner's language setting and your computer's keyboard language.
• The scanner is typically configured to the appropriate language based on the shipping region. If this issue occurs, please contact technical support for guidance on adjusting the language settings.

Q: What should I do if scanned data is not uploaded to the device?

• Check Connections: First, confirm that the terminal device and the USB interface are functioning correctly. Try connecting the scanner to a different USB port or another computer/device to rule out port or device issues.
• Input Device Conflict: Since the barcode scanner, keyboard, and mouse are all USB input devices, if your mouse and keyboard are working normally, the scanner should also be able to transmit data.
• Scanner Settings: Confirm that the barcode scanner does not have any special settings enabled, such as 'storage mode' or 'virtual serial port mode', which might prevent direct data upload. Try restoring the scanner to factory default settings (refer to the programming manual if available, or contact support).
• Reconnection: If the issue persists, try disconnecting and reconnecting the USB cable.

9. User Tips

• For optimal performance when scanning from phone screens, ensure the screen brightness is set to a high level.
• The self-sensing feature works best when the barcode is presented clearly and steadily to the scanner.
