Follow these steps to load paper:

Open the paper support, then raise the extension.

Lower the output tray, then slide out the extension.

Slide the edge guide to the left.

Fan a stack of paper, then tap it on a flat surface to even the edges.

Load the paper with the printable side up, against the right side of the sheet feeder. Then slide the left edge guide against the left edge of the paper, but not too tightly.

Note:

Leave enough space in front of the printer for the paper to be fully ejected. Always load paper into the sheet feeder short edge first, even when you are printing landscape-oriented pictures. Make sure the paper stack fits under the arrow mark inside the left edge guide.
