Scan no longer works, dialogue box does not open

[vbg-wc]

The scan function has stopped working.  I can still print but can no longer scan.  The scan dialogue box no longer opens.  It still works for the other computer on the shared network.  I have no idea why it stopped working.  I have redownloaded drivers.  Reinstalled the "network" printer and nothing works.  Any ideas?

Hello @vbg-wc ,
Welcome to the HP Support Community!

The HP software must be completely uninstalled and removed of the system.

First download only this complete package: "HP Officejet Pro 8630 e-All-in-One Printer series Full Feature Software and Drivers ", File name: OJ8630_198.exe (162.0 MB)

Then proceed as follows:

Check the system for

• TuneUp`s
• Optimization Tools
• Cleanup Tools

disable them, better uninstall them. Next...

1. Disconnect printer/scanner from computer- Disable WLAN and/or remove the USB or LAN cable.- Do not switch off the printer >> unplug the power cord from the socket!
   Only read this informations: Uninstalling the Printer Software (Windows) 
2. right-click Start, search for "control panel" and open "Programs and Features"
   uninstall all HP printer software > via "Programs and Features"
3. right-click Start, search for "control panel" and open "Devices and Printers"
   In the "Devices and Printers" window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”
4. Restart the PC
5. Close all programs
6. Change File-Explorer-Settings:View > Options > "Change folder and search options" > Tab "View"
   • enable > Show hidden files, folders and drives
   • uncheck > Hide protected operating system files (Recommended)
   OK
7. search for "HP [printer name]" and delete all this folders
8. Empty the TEMP folders
   A) C:\Users\[Your user account]\AppData\Local\Temp\
   B) C:\Windows\Temp\
system files cannot be deleted!
9. Reconnect the printer to the power supply and switch it on (if this does not happen automatically)
10. Please note: WLAN has to be deactivated!
11. Restart the PC
12. Close all programs
13. Open up the run command with the "Windows Key + R" key combo > in folder Downloads click on the EXE, see above.

Via USB, means wait until the installation asks to connect the printer/scanner.

Document error messages, even better is a screenshot and upload here.

The network configuration or the type of connection can be changed later, read Changing from a USB to a Wireless Connection 

Note:

Change the File Explorer settings again -

• enable > Don`t show hidden files, folders or drives
• click button > Hide protected operating system files (Recommended)

OK

Hope this helps! Keep me posted.
