One thing I do in order to know if its a scanner software issue or a scanner driver issue is
(assuming that you are using the Windows OS)
Go to Start - Control Panel - Scanners
Double click on it and test scan, if the scan succeeds there is a very high chance that it is actually a problem with the scanner software, look on epsons website for any firmware updates / patches for the software.
If you are scanning from a device button (directly on the hardware, not from the windows) make sure that you have a firewall port exception for the device or else the OS might reject the request since its an inbound transmission.
Hope this helps a bit.
