Can't scan since BIG Sure

HP Envy Photo 7855. I can't scan anymore and recently upgraded to Big Sur. Used to work fine before upgrade.


Tried all the advice i could find: until all HP software using HP Uninstaller. Install HP SMart andHP Easy scan. Won't connect to printer. Tried deleting printer and re adding etc. Keep getting error that it won't connect "failed to open a connection to the device - 21345".


I can print thankfully. But this is absurd!! Also tried Image Capture via Apple and it won't connect to printer either. Exclamation point in a triangle icon.


this is a brand new printer from xmas. Unacceptable. Ugh.

I tried both of them? Multiple times. Both before and after reinstalling HP software etc.


I just realized Vuescan isn't free. So while it works and that is great... it sucks to have to buy something for your higher end home HP printer to work. Unfortunate that the OS update isn't addressing this issue. Seems to be very prevalent and imo...very unacceptable to lose the ability to scan.


Any other items u did to get those methods to work?


Thanks!

I GOT IT TO WORK.


I kept thinking about that recent printer update. I then found an article about a "secret" support menu on the HP printer that would allow you to do a Semi full reset...thereby setting it back to factor specs. So i did this. During set up i used mac only to make sure i got Airprint. And i told the printer NOT to auto update.


Then i was able to scan again via the printer menu. FURTHER i am now able to scan from Image Capture as well.


WHOOO HOOOO.


Posting in case this helps someone else. Beware of auto updating the firmware of printer!


thanks to Keith and Eli.
