Configuring a Self-signed Certificate
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.
A self-signed certificate for SSL/TLS and one for S/MIME are issued separately. Update each certificate as
necessary.
Important:
c
When you update a self-signed certificate by selecting the Network Security tab > S/MIME > Client Certificate,
you cannot change Sender's Email Address on the Network tab > Email Server > Basic. If you want to change
Sender's Email Address, change all signature settings to Do not add signature by selecting the Network Security
tab > S/MIME > Basic, and then delete the self-signed certificate for S/MIME.
1. Access Web Config, and then select the Network Security tab. Next, select SSL/TLS > Certificate or S/MIME
> Client Certificate.
2. Click Update.
3. Enter Common Name.
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
