Printing on both sides (duplexing)

You can print on both sides of a sheet of media, either automatically by using the optional automatic two-sided printing accessory (duplex unit), or manually by turning the media over and feeding it into the printer again.

Guidelines for printing on both sides of a page

●Always use media that conforms to the printer specifications. See Understanding specifications for supported media.

●Specify duplex options in your application or in the printer driver.

●Do not print on both sides of transparencies, envelopes, photo paper, glossy media, or paper lighter than 16 lb bond (60 g/m2) or heavier than 28 lb bond (105 g/m2). Jams might occur with these media types.

●Several kinds of media require a specific orientation when you print on both sides of a page, such as letterhead, preprinted paper, and paper with watermarks and prepunched holes. When you print from a computer running Windows, the printer prints the first side of the media first. When you print from a computer using the Mac OS, the printer prints the second side first. Load the media with the front side facing down.

●For auto-duplexing, when printing finishes on one side of the media, the printer holds the media and pauses while the ink dries. Once the ink dries, the media is pulled back into the printer and the second side is printed. When printing is complete, the media is dropped onto the output tray. Do not grab it before printing is complete.

●You can print on both sides of supported custom-sized media by using the printer's manual duplex capabilities. For a list of supported custom-sized media, see Understanding specifications for supported media.
