Epson printers are widely used for their reliability and high-quality output. However, connection issues can prevent your printer from functioning correctly, whether it's a USB connection failure or a Wi-Fi connectivity problem. Fortunately, Epson provides a useful tool called the Epson Printer Connection Checker, which helps diagnose and resolve these issues.

In this guide, we’ll explain what the Epson Connection Checker is, how to use it, and step-by-step troubleshooting for both network and USB connectivity problems.

Once the scan is complete, the tool provides detailed reports and possible solutions to fix the detected issues.

3. Reconnect the USB cable and turn the printer back on.

Troubleshooting Wi-Fi & Network Connection Issues

If your printer is not connecting wirelessly, follow these steps to resolve the problem.

Step 2: Check Printer’s Network Connection

✔ Ensure the printer is turned on and connected to the correct network.

✔ Print a Network Status Report to check connectivity:

 

• Press the Wi-Fi button on the printer for 5 seconds.
• A report will print, showing signal strength and network status.

✔ If the printer is connected to the wrong network, reset the Wi-Fi settings and reconnect.

Step 3: Restart Your Router & Printer

1. Turn off your Wi-Fi router and Epson printer.
2. Wait 30 seconds, then turn them back on.
3. Run the Epson Connection Checker again.

Step 4: Reconnect Printer to Wi-Fi

1. On your printer, press Home > Setup > Network Settings > Wi-Fi Setup.
2. Select Wi-Fi Setup Wizard.
3. Choose your Wi-Fi network (SSID) and enter the password.
4. Print a Network Configuration Report to confirm the connection.

✔ If the printer still doesn’t connect, try using a static IP address in your router settings.

Fixing Firewall & Security Software Issues

If the Epson Connection Checker detects that your firewall or antivirus is blocking the printer, follow these steps:

1. Open your antivirus software (e.g., Windows Defender, McAfee, Norton).
2. Go to Firewall or Network Protection settings.
3. Add Epson Connection Checker and your printer software as an exception.
4. Restart your computer and re-run the tool.

✔ Now, check if the printer appears online.

What to Do If Connection Checker Cannot Fix the Issue?

If your printer still won’t connect, try the following:

✔ Use a wired (USB or Ethernet) connection instead of Wi-Fi.

✔ Reset the printer to factory settings and set up Wi-Fi again.

✔ Check your router settings—some routers block unknown devices.

✔ If all else fails, contact Epson Support for further assistance.
