Epson ColorPage 8000 Printer Manual page 23

Note
Load letter-size and
smaller paper short edge
first. Load legal-size and
larger paper long edge
first.
5. Insert the stack of paper, lining it up with the right side of the cassette.
Make sure all the paper is under the metal retaining clip.
If you're using letterhead, load it face down, with the top of the page
toward the back of the printer.
6. Slide the edge guides back until they just touch the edges of the stack of
paper. Make sure the edge guide points to the size mark that matches the
paper you're loading. This allows the printer to select the right tray for
the paper size you want when you print.
