How can I get the certificate corrected?  Radar-Sparky

Do you get an error like this when trying to connect to the printer's embedded web server?

This can be caused as many browsers reject or warn of self-signed certificates which is the type of certificate that is installed from factory, 

Security certificates work like this: The normal assumption that browser software makes is that the certificate has been issued by a certificate authority. The browser can then contact that authority to confirm that the certificate is valid. In the case of printers, typically the certificates are self singed, which work but when the browser goes to check, it sees that there is no external authority vouching for the certificate.

In layman terms, you are pulled over by the police and they ask to see your license. They look at it, call it in and it is verified against the license issuers records or other sources. That is a secure certificate.

The other scenario is that when asked for a license, you hand the officer a piece of hand written paper that states your name. So the officers asks you "are you who this says you are" You answer in the affirmative but how does the officer know if that is legitimate or not? You cannot vouch for yourself.

Please provide some more complete details about what you are experiencing.
