Epson Error I-31: Wi-Fi setup from your computer
✅ Usually fixable yourself
I-31 means the printer is waiting for Wi-Fi setup from a computer (Wi-Fi Auto Connect).
What to try
- On your computer, run the Epson installer.
- Follow the on-screen instructions to make the wireless settings.
When it needs a technician
This is not a fault. If setup fails, contact Epson support.
Which models show I-31
Epson documents this code for models including EcoTank ET-2850, EcoTank ET-2760, EcoTank ET-2650, EcoTank ET-4810, Expression XP-340, WorkForce WF-2930, WorkForce WF-110.
First steps for any printer error
- Write down the exact code before you do anything else — similar-looking codes often mean completely different things.
- Power the printer off, unplug it for a couple of minutes, then power it back on. A surprising number of transient errors clear here.
- Open the covers and check for paper scraps, packaging material, or anything blocking the carriage.
- Check the cartridges or tanks are genuine, correctly seated, and not empty.
- Confirm the printer is plugged directly into a wall outlet, not a power strip or extension lead.
- Check your model’s own manual — codes are model-specific, and the manual is the authority for your machine.
