Why won’t my scanner detect any documents?

There could be a few reasons why your scanner is not detecting any documents. The most common reason is that the scanner software may not be installed correctly on the computer, or it may be out of date. It is also possible that the scanner glass may be dirty, dusty, or scratched, which can prevent it from reading the documents correctly. Additionally, some scanners require calibration before use, which should be checked in the scanner’s settings. The power supply wire could also be malfunctioning, so it is important to check for any signs of damage or fraying.

The document itself could also be preventing the scanner from working correctly. If the text or image on the paper is not in sharp focus, the scanner may have difficulty recognizing the scan, and some scanners may only be able to distinguish between certain types of document such as paper or thin card. It is a good idea to try scanning different types of paper to see if one particular format works better than another.

Finally, it is a good idea to check the USB cable connection between the scanner and the computer, as this may be the source of the problem. Make sure that the cable is firmly connected and that there are no loose connections. It is also possible that the USB port on the computer may be damaged, so it is worth checking with a different port or cable if possible.

If all else fails, it is best to consult the manufacturer’s website or customer support hotline to see if they can provide any troubleshooting advice. There may also be a user manual available with tips on proper installation and maintenance of the device.
