I understand you are having issues while scanning. Let’s first try to fix this issue using HP Print and Scan Doctor (PSDR). PSDR is an automated tool which can diagnose and resolve printing and scanning problems. Please go to http://hp.care/2bZ9w2q to download and run HP PSDR. Once you open the program, select your printer and click on “Fix Scanning” to automatically diagnose and fix the issue.
If the issue persists, then proceed to uninstall and reinstall the drivers:
Unplug the USB cable from the printer and computer if present.
Go to Control panel – Programs and feature – Select all the HP Officejet printer entries and uninstall them.
