Computer firewall is blocking communication with the printer

Firewall settings may have stopped the printer from connecting to your computer.

If a firewall is installed on your computer, then do one of the following:

•Turn off your computer firewall.

•Update your computer firewall to the most recent version, and then allow the printer software to communicate over the network.

For more information on turning off and updating the firewall, see the help pages of your operating system.

Communication with printer lost when connected to Virtual Private Network (VPN)

You will lose your connection to a wireless printer on your local network when connected to most Virtual Private Networks (VPNs).

Most Virtual Private Networks allow computers to communicate with only the VPN and no other network at the same time. Disconnect from the VPN before installing the driver on the computer or before running the wireless setup on the computer.

To check if the computer is currently connected to a VPN, open your VPN Client software, and then check your VPN connections. If you do not have a VPN Client software installed, then check the connections manually using the Windows VPN Client.

If you would like to have the ability to connect to your local network and to a VPN at the same time, then request the system support person for the VPN to allow split tunneling. Be aware that some organizations will not allow split tunneling due to security or technical concerns.
