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.
Check the paper condition. If paper absorbs moisture, it becomes wavy or curls that may cause the trouble.
If paper jams occur frequently, try using newly opened papers.
Try disabling Print Speed Priority. On the home screen, tap Settings > General Settings > Printer Settings > Print Speed Priority, and then disable the setting.
When you punch holes using the hole punch unit installed in the finisher, adjust the data so that it is not printed at the punch position. Alternatively, set the binding margin so that it is not printed at the punch position. If you punch on the printed area, it may cause punch failure or a paper jam.
