Question Panasonic KX-MB271 Printer/Scanner; scanner function stop working

[videobruce]

Out of the blue (well almost) the Scanner function has stop working. The machine goes thru the cycle of scanning, but no file is produced. I've never had a problem with this on more than one of theses printers. Here is what I have done;

Did a search, but nothing other than a bad MS KB update that I didn't do,,
Removed and re-install the software & drivers and the update files. I have done that up to three times,
Disconnected this machine and connected another of the SAME model repeating the uninstall and re-install process,
Tried my back up, bootable HDD (D drive) )w/ the same O/S (that I rarely use, it's only for backup if I get a virus which hasn't happened in years),
Tried another USB cable,
Ran numerous A/V programs, all showed clean.

None of that fixed the problem. I thought it was a MS file thing (missing or corrupted helper files (dll's etc), but when the other drive failed I ruled that out.
The printer works fine, I can send jobs to the printer, but the scanner doesn't send the scan to the PC.

Win 7 Pro x64 on a AMD based Tower.

Any ideas??

I should add, this is not the deal with that MS KB update causing a similar problem. That update was never installed.

Check device manager for the scanner and see if it shows up as a device besides the print function.

Usually there's an app that gets triggered as well for a scan job.

Check their website for updated software. Seems since more than one device reproduced the problem it's a system issue with windows or the software.

Ok, I removed the software, mostly manually and I did two searches, one using "Everything Search" and the other using "Registry Crawler" with Panasonic the key word. Previously, I didn't search the Registry.
I reloaded the two program files and tested the scanner. It worked.
So far so good. I will keep my fingers crossed.
I'm assuming it was Registry keys, but who knows. I did make a fresh O/S backup using 'True Image'.
