7. Troubleshooting

| Scanner not reading barcodes. | Barcode damaged, poor lighting, incorrect aiming, or unsupported barcode type. | Ensure the barcode is clear and undamaged. Provide adequate lighting. Aim the laser line directly across the barcode. Verify it's a 1D barcode. Clean the scanning window. |
| Scanned data not appearing on screen. | Application not in focus, incorrect keyboard layout, or driver issue. | Click into the text field of the application where you want the data to appear. Restart the application or computer. Check device manager for driver status. |
