Greetings @Ch_22, 

Welcome to HP Forums and Thanks for the post. 

I understand that you are unable to scan from your printer using your computer running on Windows 7. 

Not to worry, I will be glad to assist you.

Kudos to you for trying a lot of troubleshooting steps on your own.

How is the printer connected to your computer? (USB or wireless.)

Have you tried to use Windows Scan software?

Recommend you to uninstall the printer using the method mentioned below and install it back. 

Uninstall the printer from "programs and features"

(Please have the printer Off and disconnected during uninstallation.)

Check in device manager, if the printer is listed there, please delete it. (Right click on the Windows button to access device manager)

Go to devices and printers, select any printer listed there and you will get some options on the top. 

Click on print server properties. 

You will get a popup, click on the drivers tab and delete all the HP printer drivers listed there, if any.

Delete all the instances of your printer listed in devices and printers.

Restart the PC.

Once the PC is on the desktop, press Win + R, it would bring a Run dialog box, 

Type %temp% in the run box and click Ok or hit the Enter button.

It would bring up the temporary files folder. Delete the files in the folder (You might not be able to delete all the files).

If possible, delete the printer from the registries using Regedit or using any other 3rd party application.

Restart the PC again. 

Download the latest full feature driver from www.hp.com/drivers and install it on the computer.

Connect the printer to your computer only when the setup prompts for the printer. 

Let me know how it goes.

Hi

Thanks for suggestions and sorry a delay in getting back (have been away for a week or so)

The windows scan is working although I could not find a scan as pdf option

I tried deleting and reinstalling and still had the same error message re the device manager and

probably I did not get rid of everything so will try that again and let you know

Fingers crossed !

Removing the temp files did the trick - thanks for the help
