Depending on the cause of the problem, do one of the following:
There is airflow in the room.
Minimize the airflow. For instance, turn the air conditioner off.
Printed sheets are curled.
Load the sheets the other way up.
There are too many stacked sheets.
Reduce the number of the stacked sheets. To do this, suspend printing and remove the stacked sheets, and then resume printing.
To suspend printing, press the [Suspend] key on the finisher.
To resume printing, press the [Resume] key on the finisher.
