Before you register the printer and create your user account, you need to connect your printer to the network so that it can be used from a computer. Follow the instructions in the "Start Here" setup guide to perform your printer's initial setup and network setup.
Install the Epson Printer Finder, then set up the Epson Connect services and create a user account.
