Risk level

Low

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

I-31 means the printer is waiting for Epson's computer installer to drive Wi-Fi setup; it is not a print-engine error. Run the correct regional installer and press OK when it begins Wi-Fi setup; if the installer was never launched, waiting at I-31 cannot progress.

Safety first

Safe checks you can perform

  • Preserve the exact state before acting
  • Select the branch from an observation
  • Synchronize the printer with the active installer

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Launch the exact regional Epson installer

What a technician must be able to justify

A technician is coming

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Launch the exact regional Epson installer

    What they doDownload the ET-2850/L4260 setup package from the regional Epson support page, close installers for other models, launch one copy with network permission and return to I-31 when prompted.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Preserve the exact state before acting

    No special tools

    Photograph I-31 and the complete LCD message. Record the exact ET-2850/L4260 regional model, whether the printer was starting, feeding, scanning, joining Wi-Fi or updating firmware, and the last action that completed normally. Do not clear the screen until that context is saved.

  2. Select the branch from an observation

    No special tools

    The code identifies a missing/active setup workflow, not the health of the Wi-Fi radio. Is the current Epson ET-2850/L4260 installer actively at its Wi-Fi setup step?

  3. Synchronize the printer with the active installer

    No special tools

    Confirm the installer names the exact family and intended SSID, then press OK on the printer only when the installer begins Wi-Fi setup. Follow one run to its final connection result. Expected result: The installer reports the ET-2850/L4260 connected to the intended network and I-31 disappears. Stop point: If the run fails once, save the installer error and network report; do not uninstall everything or factory-reset the printer yet.

What it means

The code identifies a missing/active setup workflow, not the health of the Wi-Fi radio. If the correct installer reaches the printer but setup fails, preserve its exact stage and network result instead of looping I-31.
