Is the IP address of the printer properly configured?
Configure the IP address using EpsonNet Config or the printer’s control panel. You can confirm the current setting
information with a network status sheet or from the printer’s control panel.
Is the Encryption Strength for SSL/TLS set to High?
If High is selected for Encryption Strength, Web Config can only be accessed in a browser supporting AES (256-
bit) or 3DES (168-bit) encryption. Check your browser's encryption support.
The message "Out of date" appears when accessing Web Config using SSL communication (https).
If the certificate is out of date, obtain the certificate again. If the message appears before its expiration date, make
sure that the printer's date is configured correctly.
The message "The name of the security certificate does not match···" appears when accessing Web
Config using SSL communication (https).
The printer's IP address entered for Common Name for creating a self-signed certificate or CSR does not match
with the address entered into the browser. Obtain and import a certificate again or change the printer name.

If you are using a proxy server with your printer, you need to configure your browser's proxy settings.
❏ Windows:
Select Control Panel > Network and Internet > Internet Options > Connections > LAN settings > Proxy
