Scanner not working/connecting, although printing works

[schkofler]

I have the HP Photosmart 7515. Wireless printing works but scanning does not work. From the printer I get a message that says "No computer is connected" From my desktop computer through the HP software I see a message that says "Scan to Computer is enables" with my computer desktop listed. I also got another error message saying "Scanner Unreachable" It seems to know my computer is there but cannot establish a connection. How do I resolve?

Hello @schkofler ,
Welcome to the HP Support Community!

Try first this:

1. shut down printer via on/off switch
2. switch off the router
3. shut down the computer
4. wait about 60 sec.
5. switch on the router, wait until the router has completely initialized itself again
6. Switch on the printer, wait until the printer has finished its initialization
7. switch on computer, log in (with admin rights) and wait about 10 sec.

... and now everything's working again?

If that doesn't help, here's what you need to do:

1. Uninstall HP printer software, and then remove the printer from your Devices list. 
2. Restart the PC
3. Close all programs
4. download only this complete package: HP Photosmart 7510 e-All-in-One Printer series - C311 Full Feature Software and Drivers 
5. Close all programs
6. Open up the run command with the "Windows Key + R" key combo > in folder Downloads double-click on the EXE
7. The installation was completed successfully, now you must ...
8. Restart the PC again
9. Now the installation is complete.

Document error messages accurately, even better is to take a screenshot of it and upload here.

Hope this helps! Keep me posted.
