Updating a Self-signed Certificate
Because the Self-signed Certificate is issued by the printer, you can update it when it has expired or when the
content described changes.

You can enter up to 5 IPv4 addresses, IPv6 addresses, host names, FQDNs between 1 to 128 characters and
separating them with commas. The first parameter is stored to the common name, and the others are stored to
the alias field for the subject of the certificate.
Example:
Printer's IP address : 192.0.2.123, Printer name : EPSONA1B2C3
Common name : EPSONA1B2C3,EPSONA1B2C3.local,192.0.2.123
