Administrator's Guide
❏ CA Certificate
This is a certificate that is in chain of the CA-signed Certificate, also called the intermediate CA certificate. It is
used by the web browser to validate the path of the printer's certificate when accessing the server of the other
party or Web Config.
For the CA Certificate, set when to validate the path of server certificate accessing from the printer. For the
printer, set to certify the path of the CA-signed Certificate for SSL/TLS connection.
You can obtain the CA certificate of the printer from the Certification Authority where the CA certificate is
issued.
Also, you can obtain the CA certificate used to validate the server of the other party from the Certification
Authority that issued the CA-signed Certificate of the other server.
❏ Self-signed Certificate
This is a certificate that the printer signs and issues itself. It is also called the root certificate. Because the issuer
certifies itself, it is not reliable and cannot prevent impersonation.
Use it when making the security setting and performing simple SSL/TLS communication without the CA-
signed Certificate.
If you use this certificate for an SSL/TLS communication, a security alert may be displayed on a web browser
because the certificate is not registered on a web browser. You can use the Self-signed Certificate only for an
SSL/TLS communication.

Web Config, a certificate is the PEM/DER format.

Filtering > Client Certificate or IEEE802.1X > Client Certificate.
Whatever you choose, you can obtain the same certificate and use it in common.

A CSR creating page is opened.

Available key length and abbreviations vary by a certificate authority. Create a request according to rules of each
