Press the release and open the door of the 1,500-sheet tray.
Pinch the guides at the front of the tray and slide them to the correct paper size.
If paper is in the tray, remove it. When paper is in the tray, the guides cannot be adjusted.
Load the paper into the tray. To prevent jams, load complete reams at one time. Do not divide reams into smaller sections.
Make sure that the paper does not exceed the fill marks on the paper guides, and that the front edge of the stack is aligned with the arrows.
Close the door on the tray.
