Check the following if paper jams occur frequently.
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.
For A4 or A5 size paper, change the loading direction to portrait or horizontal. If you load paper in the portrait direction, print speed may be slower.
Make sure the paper size and paper type settings match the actual paper size and paper type loaded in the printer.
