The steps below typically resolve the issue you’re experiencing:
1. Unplug the power cord from the back of the printer.
2. Unplug the power cord from the back of your router (and modem, if separate from the router).
3. Wait 20 seconds, then plug the router (and modem, if applicable) back in.
4. Wait 30 seconds, then plug the printer back in and power it on.
5. Press the ePrint button on the printer's front panel, and it should try to connect to Web Services again.
Those steps usually resolve the issue, but if it still occurs you can try setting static network info for the printer (which sometimes helps to stabilize the printer's ability to get outside of your network, to the internet):
1. Press the network icon at the top of the printer's screen and note the IP address.
2. Enter the IP address into the address bar of a web browser on a computer and press enter or click the browser's go button.
3. The printer status page should be opened. Click on Network at the top.
4. Select Proxy Settings.
Note: If you are prompted for a redirect, select OK. If you receive a certificate warning, select the option that lets you continue anyway.
If you receive a Internal System Error, refresh the page until it loads the proxy settings.
5. Verify that all fields are blank. If they are not, clear them and make sure the Proxy Server requires authentication is unchecked and click apply. You should get a success message.
6. Click on IPv4 under the correct connection (wired or wireless) on the left.
Note: If you only see IP Address Configuration and DNS Address Configuration with a yellow note, refresh the page until it loads completely.
8. Leave the IP Address Configuration as Automatic IP.
9. Change DNS Address Configuration to Manual DNS server.
10. Enter 220.127.116.11 for the Manual Preferred DNS Server and 18.104.22.168 for the Manual Alternate DNS Server.
11. Click Apply and you should get a success message.
12. Power off the printer for 30 seconds and then turn it back on to force the new settings to take effect.
