Model name and/or IP address are not displayed on EpsonNet
Config
Did you select Block, Cancel, or Shut down when a Windows security screen or a firewall screen was
displayed?
If you select Block, Cancel, or Shut down, the IP address and model name will not display on EpsonNet Config or
EpsonNet Setup.
To correct this, register EpsonNet Config as an exception using Windows firewall and commercial security
software. If you use an antivirus or security program, close it and then try to use EpsonNet Config.
Is the communication error timeout setting too short?
Run EpsonNet Config and select Tools > Options > Timeout, and then increase the length of time for the
Communication Error setting. Note that doing so can cause EpsonNet Config to run more slowly.

Solving Problems for Advanced Security

Restoring the Security Settings

When you establish a highly secure environment such as IPsec/IP Filtering, you may not be able to communicate
with devices because of incorrect settings or trouble with the device or server. In this case, restore the security
settings in order to make settings for the device again or to allow you temporary use.

Disabling the Security Function from the Printer

You can disable IPsec/IP Filtering from the printer.
A
Make sure paper is loaded.
B
Press the o and d buttons until the printer beep once and the Font and Tear Off lamps turn on.
The printer enters the default-setting mode and prints a message prompting you to select the language for
the default-setting menu. The language which is underlined indicates the current setting.
C
If the language you want is not selected, press the d button until the printout indicates the language you
want.
D
Press the o button to select the desired language.
E
If you want to print the current settings, press the o button. If you want to bypass printing of the current
settings, press the d button or the u button.
The printer prints the first menu and the current value of the menu.
