Support Printers All-In-Ones WorkForce Series Epson WorkForce Pro WF-4640

I see the message Printer is Offline when I try to print with a wireless (Wi-Fi) connection in Windows. 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 from the product's control panel.
      • If you can print, go to the next step.
      • If you can't print a nozzle check pattern, check the product's LCD for error messages. Clear any errors displayed on the LCD, then try printing a nozzle check pattern again. If you still can't print, contact Epson support.
    2. Delete any pending print job(s) from the Epson print queue and then try printing again.

      If you can print, you're done, and you can skip the remaining steps.

      If you still can't print, check the Wi-Fi icon on the product's control panel, then do one of the following:

      • If the Wi-Fi icon is lit, follow the instructions in the Initialize Your Router and Restart Your Computer section below.
      • If the Wi-Fi icon is not lit, follow the instructions in the Reinstall the Product Software section below.

    Initialize Your Router and Restart Your Computer

    1. Unplug your router's power cord from the power outlet, wait a brief period, then plug it back in. Try to print. You may need to re-establish the connection for the other devices on your network.
    2. If you can print, you're done. The problem was resolved by initializing your router.

      If you still can't print, restart your computer, then try printing again. If these steps do not resolve your problem, contact Epson support.

    Reinstall the Product Software

    Important: You'll need to know your network name (SSID) and network password before you can set up your product. If you don't know them, contact the manufacturer of your router or the person who set up your network. If you are using a 5 GHz wireless router, set the router to operate in dual band (2.4 GHz and 5 GHz) mode. See your router documentation for instructions.

    1. Reset the product's Wi-Fi settings on the product's control panel by doing the following:

      Select Setup > System Administration > Restore Default Settings > Wi-Fi/Network Settings > Yes.

    2. Turn off the product and disconnect any interface cables.

    4. Disable the firewall. If you have other firewall software enabled, you'll also need to disable it. 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 Wi-Fi setup. Remember to enable your firewall software after you complete the Wi-Fi setup.

    5. Do one of the following:
      • Windows 8.x: Navigate to the Apps screen, select Control Panel > Programs > Programs and Features. Select the uninstall option for your Epson product, then select Uninstall/Change.

        Select your product again, if necessary, then select OK and click Yes to confirm the uninstallation.

      • Windows (other versions): Click or Start, and select All Programs or Programs. Select Epson, select your product, then select EPSON Printer Software Uninstall.

    8. Unplug your router's power cord from the power outlet, wait a brief period, then plug it back in. You may need to re-establish the connection for the other devices on your network.
    9. Download the Drivers and Utilities Combo Package from the Downloads tab for your product. Make a note of the file name and save the location so you can retrieve it.
    10. Open the file you downloaded and follow the on-screen instructions. When you see the Select Your Connection screen, select Wireless connection, then click Next.

    11. When you see the Select Setup Option screen, select Set up printer for the first time, then click Next.

      If you see this screen, click Options.

    12. When you see the Select a Wireless Network Setup Method screen, follow the on-screen instructions to complete the installation.

      Note: We recommend using a temporary USB cable connection (cable not included) to simplify wireless setup. If you don't have the cable, select Using printer buttons to set up your printer.
