S/MIME

Secure/Multipurpose Internet Mail Extensions (S/MIME) is a standard for public key encryption and
signing of email encapsulated in MIME.
Before you begin:
• Enable SSL/TLS. For details, see
• If an S/MIME-capable self-signed certificate is not available, install an S/MIME certificate and all
certificates in the certification path (chain of trust) for the S/MIME certificate. The S/MIME
certificate must be in PKCS #12 format, and the email address in the certificate must be the same
as the printer's email address. For details, see
• Enable S/MIME Communication on the SSL/TLS Settings page. For details, see
HTTP and SSL/TLS Settings
