Check the paper edges are aligned at the right side.
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.
When loading a low number of sheets, be sure not to squeeze the side fences in too tightly. If the side fences are squeezed too tightly against the paper, the edges may crease, thin paper may wrinkle, or the paper may be misfed.
Carefully pull out the paper tray until it stops.
Square the paper and load it print side up.
Do not stack paper over the limit mark.
Carefully push the paper tray fully in.
