Conguring a Self-signed Certicate
Updating a Self-signed Certicate
Because the Self-signed Certicate is issued by the printer, you can update it when it has expired or when the
content described changes.
A self-signed certicate for SSL/TLS and one for S/MIME are issued separately. Update each certicate as
necessary.

When you update a self-signed certicate by selecting the Network Security tab > S/MIME > Client Certicate,

tab > S/MIME > Basic, and then delete the self-signed certicate for S/MIME.
