HP Scanning Software – Looking for Help

Asked By 20 points N/A Posted on -


I have used the HP diagnostic Utility 4.2. HPPDU and HPHNDU total successfully. 

But HPSDU stops working at the HP Twain Scan step and throw the following error:

HP Scan Diagnostic Utility 4.2


Unable to communicate with HP scanning software. Please verify that
it has been installed and is working properly. If this problem persists,
please shut down your application and try again.

If I make use of HP Setup.exe to un-fit all software and after that try to reinstall all HP software, then the scanning software will run very well. What is the reason?

I need to solve it.

Please help.

Thanks a lot.

Hallo Dawn,

You are getting an error when using your HP Scanning Software because of the following reasons:

  • A network cable may be disconnected on the computer you are trying to configure the printer on. Check also to make sure that the printer is connected to the network so that the setup will work in the event that  you are configuring from a remote computer.
  • The software registry entries may be corrupt, and therefore you will need to install CCleaner on your computer and then repair all the problems with the registries on your computer. If the problem persists you may be forced to uninstall the HP Scanning Software that you have installed on your computer and then reinstall it again to fix any bugs it may be having.

If you are running the diagnostic tool for your scanner, make sure the scanner is connected properly to your computer using the USB cable. You won’t be able to scan any document or perform any test if the USB cable is not connected to the computer. Transfer the USB cable to another USB port as needed. You should also check that the correct driver for your scanner is installed.

If this doesn’t work, try to uninstall and reinstall the software. Download the free version of Revo Uninstaller and install it. Once installed, start Revo Uninstaller then select your HP scanner software among the applications and click “Uninstall”. Follow the normal uninstall process. When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds.

This removes everything the program created on your computer. When it is finished, close Revo Uninstaller then install your HP software back. If the problem continues, try downloading the driver again from the HP website: HP Customer Support – Software and Driver Downloads.
