Changing the Paper Size in Tray 2 and 3

If a paper tray is pushed vigorously when putting it back into place, the position of the tray's side fences may slip out of place.

Do not stack paper over the limit mark.

Check that the top of the paper is aligned with the right side.

Slide the side fences until they are aligned with the paper size, and then re-lock the side fences.
