I guess there is a problem with the base station. Let me tell my story:
I got a 4820 scanner with 2020 base. All worked fine till I experimented with scanning images. After a few images (which I cannot retrieve/receive properly due to lack of software) the scanner seems dead. From time to time a short buzz sounds when triggered, but no light or else.
So I bought another 4820, a slightly different model. Seems to work fine but has to be paired with the base to get the data. Now after pairing this scanner shows the same issues as my first and refuses to scan.
I installed QiuckView and HSM-USB-Serial-Driver on a virtual machine at my MAC to flash firmware to base and scanners. But the base device does not show up in the program (althought it is shown in the USB device table). Maybe I can try on a native WindowsPC ...

These devices do fail, so that is most likely what has happened here.

One of the problems I had with my scanner is that the USB port that I had the scanner in when bad. My scanner cable was a little short and it put extra pressure on the port. After time some of the connections in the port broke. To fix the problem I had to replace the USB card in the system.

So I would recommend that you tryu the scanner on another computer and/or another USB controller to see if it works properly. If it does you know that it is the USB port. If it does not then I would look at the cable of the scanner.

Let me know if you have any more problems or questions
