Media can arrive curled in the output tray. This is caused by temperature differences during the print process. You can perform a correction procedure to prevent curled sheets in the output trays. The results of the correction are immediately effective for jobs that use these media.
For media that need a curl correction on the length and width, create two different entrances in the media catalog. The correction procedure changes the media attributes of the media in the media catalog, 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.
