❏ Self-signed certificate
Self-signed certificate is a certificate that the printer issues and signs itself. This certificate is unreliable and
cannot avoid spoofing. If you use this certificate for an SSL/TLS certificate, a security alert may be displayed on
a browser. You can use this certificate only for an SSL/TLS communication.
