•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 printer 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 5.1.

•Ensure that the recommended print side of print media is facing down in the tray, or facing up in the multi-purpose tray.
