If the scanner is not detecting documents, there are a few potential solutions.
First, make sure that the document is properly placed on the scanner glass. The document should be completely flat and centered on the glass. If it is not placed correctly, the scanner may not be able to read it.
Second, check to make sure the scanner is connected properly. Make sure the power cord is plugged in securely and the USB cable is securely connected to the computer.
Third, check to make sure the drivers for the scanner are installed on the computer. If they are not, install the drivers from the manufacturer’s website.
Fourth, check to make sure the drivers are up-to-date. Many scanners require updated drivers to work properly. Check the manufacturer’s website or the Windows Update website to see if there are any updates available.
Fifth, restart the computer and try scanning again. If the computer has been running for a long time, it may need to be rebooted in order to recognize the scanner.
Sixth, check to make sure the scanner is compatible with the computer. Some scanners may not be compatible with certain computers, so it is important to make sure that the scanner will work with the computer before attempting to use it.
Seventh, check to see if the scanner has been damaged in any way. Check for any visible damage on the scanner, such as scratches, dents, or tears. If necessary, contact the manufacturer for repair or replacement of the scanner.
Finally, if none of the above solutions solves the problem, try using a different scanner. There are many scanners on the market and some are more reliable than others. It may be worth trying a different scanner in order to determine if the problem is with the scanner itself or with the computer.
