Media can arrive curled in the output tray, caused by temperature differences during the print process. You can perform a correction procedure, to prevent curled sheets on the output trays. The results of the correction are immediately effective for jobs that use these media.
For media that need a curl correction in long-edge direction and short-edge direction, create two different entrances in the media catalogue. The correction procedure changes the media attributes of the media in the media catalogue, so that the adjustments are applied to all jobs that use these media.
NOTE
You can also find the curl correction procedure at the Trays view and at the media setting of the job properties.
Start with small increments to avoid paper jams.
You find the correction values in the system adjustment settings on the Preferences tab of the Settings Editor.
