Recommendation
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.
If the problem is not solved, choose Plain Paper in
the media type setting.
• If you are printing an envelope, chooseEnv. Thin in
the Media Type Setting of the printer driver.
• 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.
• Make sure the envelope levers inside the back cover
are pulled down to the envelope position when you
print envelopes.
NOTE
When you have finished printing, open the back
cover and reset the two grey levers back to
their original position (1) by lifting them up until
they stop.
• If creases occur with the envelope levers in the
envelope position, print with the back cover open and
feed one envelope at a time from the MP tray.
