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The message "Out of date" appears when accessing Web Config using SSL communication (https).
If the certificate is out of date, obtain the certificate again.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
