Click Create Self-Signed Certificate on the Configure Certificate page.
b Enter a Common Name and a Valid Date, then click Submit.

• The length of the Common Name is less than 64 bytes. Enter an identifier such as an IP address, host
name or domain name to use when accessing this printer through SSL/TLS communication. The host
name is displayed by default.

want to disable, and then click OK.

versions of BRAdmin

Now the self-signed certificate is saved in your printer memory. To use SSL/TLS communication, the
self-signed certificate also needs to be installed on your computer. Proceed to the next section.
