When printing an image covering a wide area, side-to-side image magnification is misregistered due to the changes in the paper feed speed of the intermediate transfer belt and paper transfer belt.
To adjust the following settings, pre-register the type of paper in use as a custom paper. For details about registering custom papers, see "Specifying a Custom Paper", Preparation.
Such misregistration may become marked when using the machine at low temperature and humidity.
