Unable to communicate with scanner

[JamJarChris]

Having a problem scanning to PC from OfficeJet Pro 8725.  I start the scan & the scanner does it's thing but the dialogue just whirs for a while then I get the message "Unable to communicate with scanner". I ran the print & scan doctor, did everything it said, no luck.  Results from this say there is not a problem. So I uninstalled & re-installed the software, tried to update firmware but this is all up to date anyway.  Problem seems to be with my PC, my wife's laptop works perfectly with scanner. I can also scan to memory stick. Scan to computer is enabled. Printing is not a problem. Don't know about fax as I don't use it. I would be grateful for any ideas.
