My wife just got a new MacBook Pro 13” with the M1 processor.
We have an HP Envy 7640 multifunction printer scanner. Tried to use the hp scan sw and recd message “you don’t have permission to use hp scanner 3”
Changed permissions for that file to R/W for all but no luck.
I can scan using hp smart app, but can only scan using the flatbed and not the document feeder.
Looking at the hp support, others have had similar issues after upgrading to Big Sur.
Anyone else having similar issues out there?

Yes earlier this week, with an Intel 2015 iMac after upgrading to Big Sur with an Epson workforce. One file deep in the library folder is the scanner plug in. Same error. Tried same resetting of permissions for the file. Tried giving the Epson scan program full disk access permissions.

The only fix I found was usb connection rather than WiFi. Resetting the printers and then plugging in the cable, the computer auto configured as secure AirPrint (rather than the newly downloaded Epson drivers) and was able to scan.

The client decided it works and stopped me from continuing to trouble shoot why the wireless wouldn’t work.

Sent from my iPhone. Some imagination required.

I just heard on macOS Ken That Apple has said that the permissions problem on some scanners is a bug of theirs.

I don’t have a link for the fix but hopefully you can find it online today.
