Model Name or IP Address Not Displayed in EpsonNet Config If the product model name and/or IP address is not displayed in EpsonNet Config, try these solutions: • If you selected the block, cancel, or shut down option on a Windows security or firewall screen, the IP address and model name cannot display in EpsonNet Config. Register EpsonNet config as an exception in your firewall or security software, or close the security software and try running EpsonNet Config again. • The operation may have timed out. Select Tools, select Options, select Timeout, and increase the time option for the Communication Error setting. This may cause EpsonNet Config to run slower, however.
