Avoiding Jams

Follow these tips to help prevent document and
paper jams.
• Use only recommended print materials.
• Do not mix paper types in the paper tray.
•
Do not use creased, damp, or curled paper.
• Flex, fan, and straighten the paper before
loading.
• Make sure the adjustable paper guides are
positioned correctly.
• Make sure the recommended print side has the
correct orientation when loading paper in the
paper tray and the manual feeder.
•
Do not overload the paper tray. The paper
should be below the max fill line on the inside
wall of the paper tray.
• Do not remove the paper from the tray while
printing.
