8.Place a sheet of the selected print media, print side facing up, at the center of the manual feeder, but only to the point where its leading edge can contact the paper guides.
Insert envelopes with the flap side facing down and with the stamp area as shown.
Hold transparencies by the edges and avoid touching the print side. Oil from your fingers that is deposited on the transparency can affect print quality.

9.Adjust the paper guides to the print media's width.
10.Hold both sides of the print media close to the manual feeder, and push it into the printer until it automatically engages.
There is a brief pause between the time the printer engages the print media and when it feeds into the printer. 
NOTICE: Do not force the print media into the feeder. Forcing the media causes jams.
Printing on Both Sides of the Paper
Printing on both sides of the paper reduces printing costs.
You can choose how you want your job duplexed: long edge or short edge.
Long edge means pages are bound along the long edge of the page (left edge for portrait, top edge for landscape).
Short edge means pages are bound along the short edge of the page (top edge for portrait, left edge for landscape).
