4. Maintenance

4.1 Cleaning

To ensure optimal performance, keep the scanner's window clean. Use a soft, lint-free cloth lightly dampened with water or a mild, non-abrasive cleaning solution. Avoid using harsh chemicals or abrasive materials that could scratch the scanning window.

4.2 Storage

Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures. Protect it from dust and physical impact when not in use.

5. Troubleshooting

• Scanner not recognized by computer:
  • Ensure the USB cable is securely connected to both the scanner and the computer.
  • Try connecting to a different USB port.
  • For iOS or Linux systems, verify if a specific driver is required and contact support if needed.
• Cannot scan Data Matrix codes:
  • Data Matrix scanning is disabled by default. Refer to Section 2.4 "Initial Configuration" and scan the FFA222 code to enable it.
• Cannot scan barcodes with black backgrounds:
  • The scanner is optimized for white backgrounds by default. Contact Kercan support for specific setting codes to enable black background scanning.
• Scanner not reading specific barcodes:
  • Ensure the barcode is clean, clear, and not damaged.
  • The scanner can read incomplete or fuzzy codes, but extreme damage may prevent scanning.
  • Verify the barcode type is supported by the scanner (refer to Section 3.2).
  • Ensure proper distance and angle when scanning.
• No beep sound after scanning:
  • The scanner typically provides an audible beep for successful scans. If no sound is heard, check if the sound function has been inadvertently disabled. Consult the full programming guide (if available) or contact support for assistance with sound settings.
