Reinstall Scanner Drivers by clicking Press win + X - Select Device Manager - expand Imaging devices or other devices - right click on those drivers and select Uninstall device then restart the computer to Reinstall drivers automatically.
You can also download and install the latest drivers from HP’s support website, specifically for the 2000s2 and N4000 series.
Install HP Scan Extended utility from HP website and check if it can detect scanners.
Also check if there is any firmware updates in HP website.
I hope this resolves your issue! If you have any queries, please let me know.
