(VPN)
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 check
your VPN connections. If you do not have a VPN Client software installed, 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, the
system support person for the VPN must enable split tunneling. Be aware that some organizations will
not allow split tunneling due to security or technical concerns.
Removing and reinstalling the software
If the printer is not functioning properly, or if a communications error message appears when you try to
use the printer, then you may need to remove and reinstall the printer software.
