I keep getting this error message when trying to set up scan-to-email:

"The printer is unable to validate the server’s security certificate because the certificate is either self-signed or has been issued by an unknown authority. To enable the printer to validate the certificate, import trusted CA (Certificate Authority) certificates into the printer.

To import the certificate, go to the Certificates page, and then follow the onscreen instructions."

I have ALREADY unchecked the Validate Server Certificate option and the error persists. What else can I do?

Welcome to the HP Support Community.

 

This could be related to security.

 

To help you further with this let us know the Printer you have and the device it is connected to.

 

Thanks 🙂
