Check the following if paper jams occur frequently.
Place the printer on a flat surface and operate in the recommended environmental conditions.
Use the paper supported by this printer.
Follow paper handling precautions.
Load paper in the correct direction, and slide the edge guide against the edge of the paper.
Do not load more than the maximum number of sheets specified for paper.
Load one sheet of paper at a time if you have loaded several sheets of paper.
Make sure the paper size and paper type settings match the actual paper size and paper type loaded in the printer.
Insert the front paper feeder completely while you are not using it. If it is not inserted completely, paper may get jammed when the printer feeds paper from the rear paper feeder.
