Disconnect the Power cord from the back of printer (while printer is on) Wait for 10 seconds, Connect the cord back and wait till it initializes. Close HP Director or HP Solution Center, Try to Scan, It should work.
Scanning requires two-way communication between the computer and the scanner. Usually the error that you describe above indicates an issue with the USB connection. First, make sure that you are not using a USB hub. Try a new USB 2.0 (A-B) cable that is under 6' long. Try using a different USB port on the computer.
If the problem persists, check the Device Manager to see if you have a USB driver problem. (For most versions of Windows, press the Windows key + X to quickly access the menu with the Device Manager.) Expand the section labeled Universal Serial Bus controllers and look for an exclamation point or an X. Similarly check for any issues in the Devices and Printers section of the Control Panel. The All-in-One should be listed as a printer and a scanner.
I hope this helps. If you are still having problems, please add a comment with the OS version on your computer. That can help identify additional issues that could be involved.

Issue When opening HP Solution Center, a message appears that states "No HP Devices Detected ".
Solution one: Check connections and status
Check to make sure that the device cables are connected securely at each end.
Make sure the device is turned on and not in an error state. If unsure, turn the unit off and then back on again.

If the device is still not detected, proceed to Solution two.
Solution two: Check that there is a printer icon in the printer folder
Click Start and then Settings or Control Panel .
Click Printers or Printers and Faxes .
Make sure there is an icon for the printer you are trying to use.
If there is no icon and you are connecting via a USB cable, disconnect the cable, and restart the computer. Reinsert the HP software CD and choose Add a device . Connect the unit when prompted by the installer.
If there is no icon and it is a wireless connection, run the wireless setup wizard as outlined in the product setup guide, then reinsert the CD and choose Add a device .
If there is no icon and it is an Ethernet connection, reinsert the CD and choose Add a device .

Click Start and then Run .
On the Open line, type D:\SETUP , where D is the letter of the CD-ROM drive.
Click OK .
