I was able to print from Windows before with a wireless connection, but now I can't. What should I do?

    The problem can be caused by your printer, computer, or wireless network. Do the following:

    1. To determine if the printer can print without a computer, print a nozzle check pattern. See these instructions.
      • If you can print a nozzle check pattern, go to the next step.
      • If you can't print a nozzle check pattern, check the product for errors and clear them. See these instructions. Try printing a nozzle check pattern again. If you can print, go to the next step. Otherwise, contact Epson Support.
    2. Delete any pending print job(s) from the Epson print queue, and try printing again. If you can print, you're done, and you can skip the remaining steps. Otherwise, go to the next step.
    3. Check your product's Wi-Fi indicator, and do one of the following:
      • If a wireless connection is established, unplug your router's power cord from the power outlet, wait a brief period, plug it back in, and then try to print. If you can print, you're done. The problem was resolved by initializing your router. If you can't print, restart your computer and try printing again. If these steps do not resolve your problem, contact Epson support.

        Note: You may need to re-establish the connection for the other devices on your network after you initialize your router.

      • If a wireless connection is not established, follow the instructions in the Reinstall the Product Software section below.

    Reinstall the Product Software

    1. Reset your product's network settings. See these instructions.
    2. Turn off the product and disconnect any interface cables.
    3. Do one of the following:

      • Windows 10: Right-click and select Control Panel > System and Security > Windows Firewall. Disable the firewall.
      • Windows 8.x: Navigate to the Apps screen and select Control Panel > Windows Firewall. Disable the firewall.
      • Windows (other versions): Select or Start > Control Panel > System and Security > Windows Firewall. Disable the firewall.

      If you have other firewall software enabled, you need to disable it also. If you don't know how to disable it, contact your firewall provider for help.

      Note: This step is needed to install the product's software and complete the wireless setup. Remember to enable your firewall software after you complete the wireless setup.

    4. Uninstall your product's software. See these instructions.
    5. Unplug your router's power cord from the power outlet, wait a brief period, and then plug it back in.

      Note: You may need to re-establish the connection for the other devices on your network.

    6. Download and install the Drivers and Utilities Combo Package from the Downloads tab for your product. Open the file you downloaded and follow the on-screen instructions to install the software.

      Note: After you complete wireless setup, turn your firewall back on.

    If this does not solve the problem, contact Epson Support.
