How do I set up Epson Connect services on the ET-3850 to enable email printing?

Press the home button, then select Settings > General Settings > Web Service Settings > Epson Connect Services, and select Register. Follow the on-screen instructions to activate your product's unique email address for use with Epson Connect. Once set up, you can print by attaching a PDF, Microsoft Office document, or photo to an email sent to your product's Email Print address, and both the email and attachments will print automatically.
