If your scanner is not being detected by a Windows system, there are several things you can try to help resolve the issue.
First, check that the scanner’s power source is connected. Ensure that the power adapter is securely connected to the scanner and to an active power source. If the scanner is battery-operated, make sure that the batteries are not depleted.
Secondly, confirm that the scanner is compatible with the version of Windows installed. Many scanners require drivers to be installed in order for them to be recognized by the operating system. If the scanner did not come with drivers included, or they were not installed properly during setup, this could explain why your scanner is not being detected by your Windows system. Try visiting the manufacturer’s website and downloading the required software and drivers. Once downloaded, install it and follow the on-screen prompts.
Thirdly, check the USB cable connection between the scanner and computer. Make sure that both ends of the cord are firmly secured in the relevant ports. Consider using a different USB cable in case the original one has been damaged. Additionally, if available, use a different port on the computer to see if the device can be detected.
Fourthly, verify that the scanner is plugged into the same power source as the computer. Make sure that the computer is plugged into an active power source. If the scanner is unrecognized even when powered on, try unplugging the computer from the electrical outlet for about a minute and then plugging it back in. This will cause the computer to reset and might help the scanner be detected.
Lastly, restart the computer. This can sometimes clear any issues with the system recognizing the scanner. Secondly, try performing a hardware scan on the computer. This allows Windows to look for any new devices that have been attached and might help detect the scanner.
If none of these steps resolve the issue, then it is possible that the scanner is defective or the connectors have become damaged. In such cases, you should contact the customer service center of the scanner’s manufacturer to arrange for a repair or replacement.
