							Printing with the front or rear manual feed slot
If you are printing one or just a few photos, envelopes, or sheets of paper, you can use the front
manual feed slot and leave your regular media in the input tray.
The rear manual feed slot uses a straight paper path and is designed for printing single sheets of
thick paper (up to 280 g/m
2) such as cardstock.
For information on media types and sizes supported by the manual feed slots, see 
Understanding
specifications for supported media.
Printing from the manual feed slots is performed in two stages: 1) changing the software settings,
and 2) loading the media. The following sections contain procedures for performing each stage.
NOTEIf the duplex unit is installed and you want to print using the rear manual feed slot,
replace the duplex unit with the rear-access panel.

							Printing on both sides (duplexing)
You can print on both sides of a sheet of media, either automatically by using the duplex unit or
manually by turning the media over and feeding it into the printer again.
Guidelines for duplexing
●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, or glossy media. Jams
might occur with these media types.
●
Do not print on both sides of paper lighter than 16 lb bond (60 g/m
2) or heavier than 36 lb bond
(135 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, paper with watermarks, and paper with 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.
●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-size media by using the printers manual duplex
capabilities. For a list of supported custom sizes, see 
Understanding specifications for supported
media.
Duplexing (Windows)
NOTEFor automatic duplexing, ensure the duplex unit is properly installed. If the rear-
access panel is installed, the printer will print on one side (simplex).

Guidelines for duplexing and Loading media.
2.With a document open, on the File menu, click Print, and then choose Properties, Document
Defaults, or Printing Preferences.
3.Click the Finishing tab.
4.Select the Print on Both Sides check box.
5.For automatic duplexing, ensure that Use auto-duplex unit is selected. For manual duplexing,
ensure the option is cleared. See

6.To automatically resize each page to match the documents onscreen layout, ensure Preserve
Layout is selected. Clearing this option may result in unwanted page breaks.
