EPSON Scanner software times out after 15 minutes of inactivity

An EPSON multi-function printer/scanner is installed on the same WiFi network as a Windows 7 computer. After 15 minutes of inactivity, the EPSON scanner software will generate a fatal time-out error message box. When clicking on the message box, the EPSON scanner software closes. I'm trying to prevent this from happening. My fist step was to see if the EPSON software was being blocked at all by a firewall. It was, and I temporarily allowed necessary connections. But the issue persists. What is the next step to diagnose this issue in order to prevent the time-out error?
