The All-In-One is set to obtain an IP address automatically, and the IP address may change each time you power on your product. If the IP address has changed, you will need to reconfigure the Epson Scan Network Settings. To prevent the IP address from changing, set your DHCP server to reserve an IP address for your All-In-One (set a static IP address) - follow the instructions below and then see your router’s documentation for details.

Confirm the scanner's IP address

You can check the current IP address of the All-In-One either via the printer's control panel (Setup > Network Settings > Confirm Network Settings), a network status sheet, or EpsonNet Config (accessible from Programs/All Programs in Windows, or Applications in Mac OS X.

You can check the Epson Scan Network Settings via start > All Programs/Programs > Epson Scan > Epson Scan Settings (Windows) or \Applications\Utilities\Epson Scan Settings (Mac OS X).

Notes Icon Note:

If you have more than one networked Epson scanner or All-In-One, you will need to make sure you select the correct All-In-One from the drop-down menu in Epson Scan Settings.

  • Make sure the Network option is selected rather than Local.

  • If the IP address in Epson Scan Settings matches the printer's current IP address, then the settings are configured correctly. See Testing the scanner for help.

  • If the IP address in Epson Scan Settings is different to the printer's current IP address, you will need to reconfigure the Epson Scan Network Settings. To do this, click on the All-In-One name under 'Network Scanner Address' (in the 'Network' section) and click the Refresh button.

    Alternatively, click on the All-In-One name under 'Scanner Name' and click on the Delete button. Click on Add to search for the scanner again; click on the scanner when it is found and click OK.

    If the search times out/the scanner is not found, make sure that the All-In-One is powered on and click Retry. Alternatively, click on the radio button beside Enter address and type-in the IP address stated on the Confirm Network Settings screen, network status sheet, or in EpsonNet Config, and then click OK.

Testing the scanner

In the main Epson Scan Settings screen, click on the All-In-One name under Network Scanner Address and then click on Test. If the test is successful, the scanner is ready to use.

If the All-In-One cannot be detected in Epson Scan Settings or the test fails, make sure that Epson Scan (escndv.exe in Windows) and Epson Scan Settings (escfg.exe in Windows) is not blocked by your computer's firewall. Also check that your firewall isn't set to block traffic from a safe network range (such as your home network

Failing this, check if the access point has any limitation for network access: check if MAC address filtering is enabled on the access point. If access restrictions are set, register the All-In-One's MAC address on the wireless router or access point. Print a network status sheet or refer to the sticker on the back of the printer to find out its MAC address. Then refer to your router or access point's documentation for instructions.
