What to check first
Step-by-step checks
- 1
Safe first step
Review the printer's network settings and compare them with the router or network details.

Switch back to automatic network configuration if manual settings are not required.
- 3

Background
What this message usually means
Epson shows this network message when the ET-3830 / ET-3850 / L6270 family has an IP address and subnet mask combination that does not make sense for the current network. This is a networking configuration problem rather than a print-engine fault.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
Diagnosis
Likely causes
The printer has invalid manual IP settings.
A subnet mask or gateway setting does not match the current network.
The device was moved to a different network without refreshing its network configuration.
Service
When service or replacement is more likely
- -This is a network configuration message, not a paper or ink fault.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
- -Assuming any supply-related wording means the next step is automatically to buy a cartridge, toner, drum, or printhead.
- -Assuming no physical path issue exists just because no full sheet is visible at first glance.
