are positioned correctly.
• Do not overload the tray. Ensure that the paper level is below the
paper capacity mark on the inside wall of the tray.
• Do not remove paper from the tray while your machine is printing.
• Flex, fan, and straighten paper before loading.
• Do not use creased, damp, or highly curled paper.
• Do not mix paper types in a tray.
• Use only recommended print media. See page
5.8
.
• Ensure that the recommended print side of print media is facing down
in the tray, or facing down in the multi-purpose tray.
