8. Troubleshooting

8.1 Common Issues and Solutions

Problem: Some barcodes cannot be read.

Solution:

• Ensure the barcode is clean and clear. Dirty or unclear barcodes might not be readable.
• Digital barcodes displayed on phones/tablets might not be readable by laser scanners (e.g., C830, NT-L6). Use a CCD or 2D imager model (e.g., C750, C850, NT-L5) for screen scanning.
• You may need to activate a specific barcode type. Refer to your configuration manual or contact customer support for command barcodes.

Problem: Data Matrix codes (e.g., on cigarettes) are not scanning correctly or with errors.

Solution: This often requires specific programming. Try scanning the code for an English keyboard layout from your configuration manual. If issues persist, contact customer support for specific Data Matrix setup codes.

Problem: Bluetooth connection fails or the phone doesn't see the scanner.

Solution:

• Ensure the scanner is in pairing mode (blue LED flashing).
• On your device, turn Bluetooth off and on again.
• Try resetting the scanner to factory defaults (refer to your configuration manual for the reset barcode).
• Ensure no other Bluetooth devices are interfering.

Problem: The scanner beeps twice and doesn't scan.

Solution: This indicates a low battery. Charge the scanner immediately using the provided USB cable.

Problem: Wireless dongle connection stopped working.

Solution: Try reconnecting the dongle. If the issue persists, try a wired USB connection or Bluetooth connection as an alternative.

Problem: Messy code problem when using foreign languages.

Solution: The default language is English. Refer to the "Language Setting" chapter in your configuration manual to change the setting.
