7. Troubleshooting
If you encounter issues with your MS840 scanner, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner not powering on. | USB cable not properly connected or faulty USB port. | Ensure the USB cable is securely connected to both the scanner and the computer. Try a different USB port on your computer. |
| 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. |
| Scanner beeps but no data. | Data transmission issue or application not ready. | Ensure the cursor is active in the target application. Try scanning into a simple text editor like Notepad to isolate the issue. |
