Product: HP Color LaserJet Pro MFP 3301sdw

My operating system is actually macOS 15, but that was not an option.

 

When I try to sign in, either using "Printer User" or "Device Administrator", and I enter the PIN, I always get "Invalid Sign-In - The sign-in attempt was unsuccessful."  I've tried changing the password, but that doesn't work.  Interestingly, I can access the EWS via Safari, but not Chrome on my computer.  Not sure where to go next.  Suggestions?

 

I'm trying to set up Scan to Email.  Thanks.
