Remedy
Locate the machine in a room that has consistent and suitable temperature and humidity. Keep the paper in the same environment as that where the machine is located. For the appropriate temperature and humidity, see other guides such as the User's Guide.
To improve this situation, adjust the value for <Adjust Gloss/Fine Black> to match the specific characteristics of the paper.
