Epson Network Report Code E-11
Network setup is incomplete, with Epson specifically calling out the default gateway as an important value to verify.
Error meaning
Network setup is incomplete, especially the default gateway.
This meaning is tied to the reviewed family/platform and subsystem below; do not reuse the number or wording by itself on a different printer family or protocol.
Applies to
ET-3930/ET-3940/ET-3950 Series
- ET-3930
- ET-3940
- ET-3950
Common formatting
These are formatting/lookup aliases for this reviewed condition, not separate error pages.
- E-11
- e-11
What usually causes it
- The printer has an IP address but no valid default gateway.
- Manual network setup was stopped before all required TCP/IP values were entered.
- The gateway changed after a router or VLAN change while the printer kept older settings.
What to try
Check whether the printer has a gateway value
Read the network report and compare the gateway with the router address used by other devices on the same network.
Complete the TCP/IP settings
If using manual addressing, enter the administrator-approved IP address, subnet mask, and default gateway as a consistent set.
Prefer automatic addressing when there is no reason for a static IP
DHCP can supply the gateway and other values together and avoids incomplete manual configuration.
Rerun the network report
Confirm E-11 clears and the printer can reach resources beyond its local subnet if your workflow requires that.
After each corrective action
Retry the same operation that produced E-11. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If E-11 continues despite a valid gateway, verify the printer is on the intended network/VLAN and that the gateway is reachable from that segment.
When service may be needed
Incomplete gateway configuration is a network setup problem, not a printer hardware fault. Escalate to the network administrator if the correct values are rejected or cannot be saved.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
