Scanner not detected by computer
Your computer and scanner have lost connection. Restart both devices and check the USB cable is plugged in firmly. If that does not work, reinstall the scanner driver. This fixes it in all cases.
When your scanner is not detected, it is because the cable is loose, the scanner driver got corrupted, or the computer needs to recognize the scanner again. We will check the cable, restart both devices, and reinstall the driver if needed.
