Paper Advance Calibration
The purpose of this Service Calibration is to calibrate the nominal advance of the paper. This calibration is
necessary to control the exact movement of the paper in order to avoid print quality problems like banding.
If you need to perform a Paper Advance Calibration to solve a print quality problem, it is recommended that
you first try the Paper Advance Calibration from the user's menu, which will calibrate the product to a specific
paper type.
