In most cases, an automatic gradation adjustment is sufficient to deliver the required colour quality. However, in the following situations it is necessary to perform also the shading correction:
After the installation of the print system.
When the printed output shows uneven colour densities in the colour panes.
When your Service organisation replaces system parts.
When different supported calibration media are loaded and assigned, the correction procedure will select the media with the largest size. Both coated and uncoated media are suitable for this procedure.

IMPORTANT
You must always perform a printer calibration before you continue with this procedure.
When the shading correction fails with a "density not within required range" error, perform a correction procedure for this error. (Fix "density not within required range" error)
