If your model has a built-in duplexer (WorkForce 633 and 635 Series), you can print a document automatically on both sides of the page using either plain paper or Epson Bright White Paper.
Note:
If you are using Epson Premium Presentation Paper Matte Double-sided, you must print double-sided manually (this type of paper is not designed to work with the duplexer). With Windows, you can
select an option in the driver to help you with manual double-sided printing.
If your model has two-sided scanning capability (WorkForce 635 Series), you can use the ADF to scan both sides of a multipage document. If you’re copying the document, you can have the copy printed on either one side or both sides of the page.
