Depending on the cause of the problem, do one of the following:
Coated paper is being used.
In the [Finishing: Finisher] group on the [Adjustment Settings for Skilled Operators] menu, set 0617: [Adjust Output Fan Level] to [Increase Air Volume].
There is airflow in the room.
Minimize the airflow. For instance, turn the air conditioner off.
Printed sheets are curled.
<If the decurler unit is used>
In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Skilled Operators] menu, select 0304: [Adjust Paper Curl] and adjust the degree of decurling.
To correct curls facing up, specify "Adjust 
Curl".
To correct curls facing down, specify "Adjust 
Curl".
Select "Strong" or "Weak" depending on the degree of decurling required.
<If the decurler unit is not used>
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.
Thin coated paper is used.

To follow the steps below, attach the decurler unit.
In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Skilled Operators] menu, set 0304: [Adjust Paper Curl] to "Adjust Curl". To control the level of decurling, select "Weak" if the present setting is "Off" or "Strong" if the present value is "Weak".
