Problems Using Network Software

Cannot Access Web Config

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.

Does your browser support the bulk encryptions for the Encryption Strength for SSL/TLS?

The bulk encryptions for the Encryption Strength for SSL/TLS are as follows. Web Config can only be accessed in a
browser supporting the following bulk encryptions. Check your browser's encryption support.

80bit: AES256/AES128/3DES

112bit: AES256/AES128/3DES

128bit: AES256/AES128

192bit: AES256

256bit: AES256

The message "Out of date" appears when accessing Web Config using SSL communication (https).

If the certificate is out of date, obtain the certificate again.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.

The printer is being accessed via a proxy server.

If you are using a proxy server with your printer, you need to configure your browser's proxy settings.

Select 

Control Panel

 > 

Network and Internet

 > 

Internet Options

 > 

Connections

 > 

LAN settings

 > 

Proxy server

, and

then configure not to use the proxy server for local addresses.

Example:
192.168.1.*: Local address 192.168.1.XXX, subnet mask 255.255.255.0
192.168.*.*: Local address 192.168.XXX.XXX, subnet mask 255.255.0.0
