Because the Self-signed Certificate is issued by the scanner, you can update it when it has expired or when the content described changes.
Access Web Config and select the Network Security tab > SSL/TLS > Certificate.
Click Update.
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:
Scanner's IP address : 192.0.2.123, Scanner name : EPSONA1B2C3
Common name : EPSONA1B2C3,EPSONA1B2C3.local,192.0.2.123
Specify a validity period for the certificate.
Click Next.
A confirmation message is displayed.
Click OK.
The scanner is updated.
You can check the certificate information from Network Security tab > SSL/TLS > Certificate > Self-signed Certificate and click Confirm.
