Recommendation
 Make sure that the paper or other print media is loaded correctly in
the paper tray and that the guides are not too tight or too loose
against the paper stack.
 Set the paper guides correctly.
See Loading paper and print media uu page 9.
 If you are using the MP tray, see Loading paper in the multi-purpose
tray (MP tray) uu page 11.
 The paper tray may be too full.
See Loading paper and print media uu page 9.
 Check the paper type and quality.
See Acceptable paper and other print media uu page 18.
 Check for loose objects such as torn paper inside the machine.
 If the problem only occurs during duplex printing, check for torn paper
in the duplex tray, verify that the duplex tray is inserted completely
and verify that the back cover is closed completely.
 Check the paper type and quality. High temperatures and high
humidity will cause paper to curl.
See Acceptable paper and other print media uu page 18.
See Product Safety Guide: Choosing a location.

paper tray too long. Turn over the stack of paper in the paper tray.
Also, fan the paper stack and then rotate the paper 180° in the paper
tray.
 Open the back cover (face-up output tray) to let the printed paper exit
onto the face-up output tray.
