Why doesn't my computer recognize the scanner?

(1) Please check whether the USB cable is connected and the memory card is installed.
(2) After connecting the computer with the USB cable, the scanner will appear in your computer as a flash memory.
(3) If the scanner is still not recognized, please replace the USB port of the computer and reconnect it, because some USB ports of the computer have poor compatibility.
(4) If the scanner still cannot be recognized after the above checks, it should be a hardware problem, please contact us for a replacement.
