paper to avoid staining or scratching the surface.
2. Roll up the paper in a direction opposite to paper curl as the figure 
below.
3. Check the printing paper if paper is corrected within approximately 2 to 
5 mm / 0.08 to 0.2 in (B).
It is recommended to print the curl-corrected paper one sheet at a time.
