When Black Spots are Generated on Print Image

The black spots on a print image may be improved by the [Fusing Roller Cleaning].
1. Load a paper (A4 or LT size plain paper) to the by-pass tray.
2. Perform the [Fusing Roller Cleaning] (toners are consumed).
[User Tools/Counter] key > Maintenance > Fusing Roller Cleaning
3. A paper is fed and images are printed on both sides of the paper.
4. Check that the black spots do not appear any more.

The effectiveness of the fusing cleaning varies depending on the types of images printed
or papers used until now. Therefore, the problem may be improved by performing the
[Fusing Roller Cleaning] several times, which consumes the toners.
