Mac OS Big Sur

[dbee73]

I downloaded the mac OS Big Sur yesterday. This morning I tried to use the scanner function on my 7740 via HP Easy Scan, and the scan crashes. Any suggestions on how to fix this?

Hi @dbee73,

Confirm you are using AirPrint by adding the printer in System Preferences.

1. Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

After installing Big Sur, I too was not able to scan.  I uninstalled all the HP apps and drivers and reinstalled.  This got rid of the 'HPDF damage' error, but I was still not able to scan from printer, using Easy Scan or using HP Smart.  I turned printer Off and On, and I can now print using HP Easy Scan and  HP Smart, but I still cannot initiate scan from the printer - "No Computer Found" message.  So my computer can find the printer, but the printer cannot find the computer...

Thanks Jay.  I installed HP Smart App after deleting the HP Easy Scanner App, and I can Scan fine now.
