"easy" scan message: scanner reported an error

[imsotired]

Just bought and set up a new Envy4520. Installed and uninstalled the software 3 times with same result. Printing works fine. I can scan one page by pushing scan button on the printer. But Easy Scan does not work. Every time I get the same error message: Scanner Reported an Error, Snvy 4520 series is currently unavailable. Please check if it is turned on and connected. Obviously it is turned on.

I previously had an Envy and the Easy Scan function worked great. I'm about to chuck this thing in the dumpster unless someone can help me.

Hi,

Thanks for using the HP Forums.

Can you try this:

From the Applications folder delete any existing HP Scan or HP Easy Scan app.
Delete HP Scan or HP Easy Scan by moving it to trash, then empty the trash.

Ensure the latest software is installed, use this link for your printer:

macOS X : HP Easy Scan

Also, make sure that your drivers are up to date

> Click on the Apple icon, select About this Mac and then press Software Update
>Click Store on the top menu bar, click Reload Page, click Update All if any updated are available.

Hope that helps!
