Recommendation
 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 15.)
 If you do not use the machine often, the paper may have been in
the 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) for the machine to eject
printed pages onto the face-up output tray.
 Make sure that the paper is loaded correctly. (See Loading paper
uu page 8.)
 Check the paper type and quality. (See Acceptable paper and
other print media uu page 15.)
 Turn over the stack of paper in the tray or try rotating the paper
180 in the input tray.
