Epson's guide describes several ways to connect, and its status codes explain the prompts. The simplest is the Epson Smart Panel app on iOS or Android, or the Wi-Fi Setup Wizard in the control panel: choose it and press OK, select your network name and enter the password. For push-button setup Epson's code I-22 says to press the button on the router or access point, or click the button on its wireless settings screen.
The checks in more detail
For PIN setup, I-23 says to enter the PIN shown on the LCD into the router, access point or computer within two minutes; after that a time-out occurs and the code changes, so you must enter a new one. Code I-31 says to make the wireless connection settings from your computer by running the installer and following its instructions. The guide also covers Wi-Fi infrastructure mode setup, selecting wireless network settings from the control panel and network security recommendations.
Set up near the router, use the 2.4 GHz network if the model needs it, and avoid special characters in the password. If the printer cannot find the network, restart the router, move closer and repeat. After setup print a network status sheet to check the signal, and reserve the address on the router. If the network changes, run the wizard again. I-41 says the Paper Setup Auto Display must be enabled to use AirPrint, and I-60 covers Scan to PC WSD support.
Write the network name and password on a note beside the printer before you start, and set up near the router. Once it works, move it and print the network status sheet again to confirm the signal. If your router has separate names for its two bands, join the printer to the one it supports, and avoid a name with special characters. Use the network status sheet's address to open the printer's own web page from a computer, which lets you check wireless settings without walking to the printer.
Differential
Likely causes of “Epson printers will not connect to Wi-Fi”, and how to tell them apart
- 1
A PIN timed out
What separates it The screen shows code I-23 because the PIN timed out
How to confirm Enter the new PIN within two minutes, before it expires
- 2
A wrong password
What separates it The printer cannot join because the wifi password is wrong
How to confirm Retype the password carefully, checking capital letters and symbols
- 3
The wrong band
What separates it The printer cannot see the network because it is on the wrong band
How to confirm Use a 2.4 GHz network, if your model requires that band
- 4
A far router
What separates it The signal is weak because the router is far from the printer
How to confirm Move the printer closer to the router, and try the setup again
- 5
A changed router
What separates it The connection is lost because the router was changed
How to confirm Run the Wi-Fi Setup Wizard again, to join the new network
Before you touch a setting
Record this first — changing settings destroys the evidence
- The signal on the status sheet
- Whether the router has been changed recently
Try in this order
0 of 7 completedOpen the Wi-Fi Setup Wizard
ReversibleOpen the Wi-Fi Setup Wizard on the printer, or use the Epson Smart Panel app.
Choose the network
ReversibleChoose the network from the list, and enter the password when it asks you, and then test again to see whether it helped.
Use push button or PIN
ReversibleUse the push button or the PIN method, if the router offers those options, and then test again to see whether it helped.
Watch the two-minute PIN limit
ReversibleWatch the two minute limit for the PIN, and enter it in time, and then test again to see whether it helped.
Print a network status sheet
ReversiblePrint a network status sheet, and check the signal strength that it shows, and then test again to see whether it helped.
Reserve the address
ReversibleReserve the address on the router, so that the printer keeps the same address, and then test again to see whether it helped.
Repeat after router changes
ReversibleRepeat the setup after router changes, by running the wizard again, and then test again to see whether it helped.
Model-specific
What is true of this model and not of its siblings
- Ethernet
- The ET-4850 and WorkForce Pro models also have Ethernet.
- Bands

Stop boundary
When this stops being a self-service repair
- !If setup fails after repeating near the router, use the computer installer route
- !If the printer sees no network, contact Epson
- !If AirPrint is unavailable, enable Paper Setup Auto Display

Common questions
What if the PIN expires?+
If the PIN expires, a new code appears, so enter that one instead.
Should I print the status sheet?+
Yes, print the status sheet, since it shows the network name and the signal.
