Can network connectivity issues cause a wireless Epson printer to enter an error state, and how can I diagnose this?

Yes, network connectivity issues are a common cause for wireless Epson printers to show an error state or appear offline. First, ensure your Wi-Fi router is functioning correctly. Then, verify that your printer is connected to the correct network and has a stable signal. You can often print a network status sheet directly from the printer's control panel to check its IP address and connection status. Restarting both your router and the printer can often resolve temporary network glitches.
