Recommendation
 Make sure the two grey levers inside the back cover are in the
up positions (1) by lifting them up until they stop.
 Make sure the media type setting in the driver matches the
type of paper you are using (see Acceptable paper and other
print media on page 32).
 Choose Improve Toner Fixing mode in the printer driver
(see Software and Network User's Guide).
If this selection does not provide enough improvement,
change the printer driver setting in Media Type to a thick
setting. If you are printing an envelope, choose Env. Thick in
the media type setting.
 Choose Reduce Paper Curl mode in the printer driver
(see Software and Network User's Guide).
If the problem is not solved, choose Plain Paper in the media
type setting.
If you are printing an envelope, choose Env. Thin in the
media type setting.
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.
 Store the paper where it will not be exposed to high
temperatures and high humidity.
Open the back cover (face-up output tray) to let the printed

paper exit onto the face-up output tray.
