There are several potential causes for a scanner not working on Windows 10.
The first possibility is a compatibility issue. If the scanner is not compatible with Windows 10, it will not be able to function properly. To determine if this is the problem, check the manufacturer’s website to see if the scanner is supported by Windows 10. You can also find out if there are any updated drivers for Windows 10 that are needed. If you have an older scanner and there are no supported drivers, then the scanner may need to be replaced in order to work with Windows 10.
Another potential cause is a conflict between the hardware and software. If you connect the scanner to the computer and it is not detected, then there could be a hardware or software conflict. This can happen when the wrong drivers are installed, or when sound and video cards on the computer interfere with the scanner. To rectify this, update the device drivers on your computer and uninstall any unnecessary programs that might be causing problems.
A third possible cause is inadequate power. Most scanners require USB connections to draw power from the computer, but they might also need external power sources. It’s possible that the USB port on the computer is either not supplying enough power or is no longer functional. Try connecting a different USB port or using an external power adapter.
Finally, if the scanner still doesn’t work after trying these solutions, it is possible that the device itself is faulty. Try cleaning the scanner using compressed air and check for any loose or broken parts. If nothing else works, contact the manufacturer for additional support and potentially a replacement device.
