- Handling: While the device is designed to be durable, avoid unnecessary drops or impacts. Handle the USB cable carefully to prevent damage to the connectors.
6. Troubleshooting
If you encounter issues with your barcode reader, consider the following:
- Scanner Not Reading:
- Ensure the USB cable is securely connected to both the scanner and the host device.
- Verify that the scanner is in the correct operating mode (Key Trigger or Continuous).
- Check if the barcode is damaged, smudged, or poorly printed.
- For screen scanning, ensure the screen brightness is at maximum.
- Some densely packed or ambiguous PDF417 barcodes, or other special 2D codes, may not be scannable or enabled by default. Refer to the full product manual for advanced configuration options to enable specific barcode types.
- Incorrect Data Output:
- Check the scanner's configuration settings (prefix/suffix, character deletion) by referring to the full product manual and scanning the appropriate setup barcodes.
- Ensure your host system's keyboard layout matches the scanner's output settings (e.g., Japanese keyboard output support).
- No Power/Indicator Light:
- Confirm the USB cable is properly connected and the host device is powered on.
- Try connecting the scanner to a different USB port or a different computer to rule out port issues.
