OfficeJet Pro 6978 scanning error

[Vinod9340]

My scanner is not working for couple weeks now and I have tried the most common solutions that are available to correct the problem including restarting, rebooting, reconnecting, updating driver and using HP smart help but still scanning feature does not work. Here the message that I get on the printer screen-

Server Problem

The printer could not connect to web services. The server might be busy or temporarily unavailable. Try again later.

All other printing services are working. I am connected to my network through wifi and printing services through that are working fine.

Hello,

This is unfortunately a very common problem lately, it's clearly an issue with the HP Smart app itself.

Please check that your printer is not in the list linked here below

HP Printers - Web Services Stop Working | HP® Customer Support

I suspect the HP Smart app is somehow using web services to communicate with the scanner that now aren't supported anymore, you will in fact notice that if you try to scan from the HP smart app, while you are getting the "cannot communicate with the scanner" error, the scanner is actually working.

For the moment I suggest you to use third party software (e.g. Scanner app by Microsoft from Microsoft store if you have Win 10, with that the scanner is working flawlessly) until HP doesn't fix the problem.
