When using an Epson application, there are cases where the Windows Firewall will block the application from accessing your network. If this happens, the installation will fail. This issue can also occur with commercially-available antivirus and firewall software, such as those produced by Symantec (Norton)
In Windows XP SP2 / SP3, Windows Vista, Windows 7,8 and Windows 10 the default setting is that the Windows Firewall is turned On. You should add an exception for the Epson application in the Windows Firewall if the printer cannot be found during setup or you cannot connect to the network through the application. The method for adding an exception is explained below.
When you add an exception in the Windows Firewall, the port can be used by the registered program(s) and will be able to receive external transmissions e.g. from another computer or printer. This means that this port may pose a security risk for attacks via the network. Consider that there is a real risk of a virus invading your computer. It is the customer's responsibility to assess the risk before changing the firewall settings. Epson cannot be held responsible for any damage resulting from changing the settings.
The example here uses 'EPSON Scan' and 'EPSON Status Monitor'. If you are using a different application, expand the section below which contains the locations and paths for common Epson software packages.
Software default locations
The software is installed to the drive that Windows is installed on - normally (C:). If this is not (C:), please change the drive letter from (C:) to the correct value for your system environment.
A list of programs will appear under Allowed apps and features. Check the list for any Epson programs such as EPSON Status Monitor, EPSON Network Utility, EPSON Scan, EPSON Scan Settings. Click into the box beside the program (under "Name") to allow it through Windows Firewall and check each box for "Home/Network (Private)" and "Public".
If you have located these programs and allowed them, click OK. If you are unable to locate these programs in the list, you can locate the program and add it to the list. To do this, click on the Allow another app... button.
If the program is listed, click on the program to highlight it and then click OK. Then repeat step 4 to allow the program through Windows Firewall.
If the program is not listed, click on the Browse button to select an application.
Choose the application from the folder, you may have to browse to the program files directory and select the appropriate .exe file for the application.
Click Open or OK.
Confirm that the added application appears in the check box and then click OK.
If you wish to remove the added application from the exception list, select the application in the Windows Firewall Settings window to highlight it, and then click on Remove:
