What usually causes it
- The SSID was typed incorrectly, renamed, hidden, or is not available where the printer is located.
- The Wi-Fi password/security key is wrong, including capitalization or special characters.
- The printer is trying to join a guest, extender, or similarly named network instead of the intended router SSID.
What to try
Confirm the exact Wi-Fi name
Compare the SSID with a phone or computer that is connected to the intended network. Similar network names are easy to confuse.
Re-enter the wireless password carefully
Use the current router password, preserving uppercase/lowercase letters and symbols. Do not use the router admin password unless it is also the Wi-Fi key.
Move closer to the intended access point for setup
If the SSID is intermittent, reduce distance or interference long enough to establish the connection.
Run the Epson connection report again
After correcting SSID or key, generate a fresh report so you can see whether E-2 clears or changes to a more specific network issue.
After each corrective action
Retry the same operation that produced E-2. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If E-2 persists with a verified SSID and password, check whether the network is hidden, uses unsupported security, or is being provided by a different access point than expected.
When service may be needed
This code is usually resolved in Wi-Fi configuration. Epson support may be appropriate if the printer cannot see a nearby compatible network that other devices can use.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
