Unknown device for Officejet Pro 8620 after upgrade to Win10 1703

[adunkhor]

Hi folks,

after the upgrade to Windows 10 Build 1703 the Officejet Pro 8620 is always shown as unknown device.

The error is "No compatible driver found".

I already uninstalled all the HP stuff and reinstalled the driver offered at the HP web site (dated 2015).

No improvement.

What am I doing wrong?

Or do I have to switch back to 1607?

Thank you.

Cheers Axel.

Hi! @adunkhor, Thanks for stopping by HP forums!

I understand your printer is listed as unknown device after upgrading to windows 10.

Don't worry I will try to help you out.

Did you make any changes to your printer?

As you mentioned you have uninstalled and reinstalled the printer drivers but the issue still persists.

Please uninstall the printer drivers from root level on your PC and install the printer basic driver and check if it helps.

1. Navigate to Start >Type Devices and Printers in the Search > Select it from the results

2. Highlight your printer object and Right Click

3. Choose Remove Device

4. Highlight something else from the list

5. Click the Print Server Properties button from the toolbar

6. Select the Drivers Tab

7. Highlight the appropriate print driver

8. Click Remove

9. Check the Remove Driver and Driver Package option when prompted

10. Click OK

Please update the printer basic driver using this link.

Let me know how it goes!

Have a great day ahead! 🙂
