2. General 
 
Depending on the paper type such as paper which generates a lot of paper dust, the 
upper heat roller may be marked with tiny scratches and toner may adhere to the 
scratched parts, resulting in toner staining of the copy paper. 
 
For the machines where toner adheres to the upper heat roller, the upper heat roller whose 
coating agent has been changed from PTEE to PFA to improve peelability of paper dust and 
toner is newly supplied as a service part. 
3. Cause 
Normally, a small amount of toner which was not fixed to the paper and was attached on the 
upper heat roller adheres to the next paper or the lower heat roller. Toner does not get stuck 
to the upper heat roller. 
However, depending on the component contained in the paper, the coating on the upper heat 
roller may be marked with small scratches. It is presumed that adhesion of toner to the 
scratched parts results in this phenomenon. 
We think that when using paper which generates excessive paper dust, fusing of toner to the 
paper decreases and toner is more likley to stick to the upper heat roller. 
4. Note 
As mentioned above, adhesion of toner to the upper heat roller is mainly caused by paper 
which generates a lot of paper dust; toner is not sufficiently fixed to the paper. 
Therefore, advise end users to use a better quality paper.

When replacing with the new upper heat roller although the paper which is easy to generate 
paper dust (paper with lower toner fixability) is still used, the back of paper may be stained 
since toner which was not fixed to the paper adheres to the lower heat roller through the 
upper heat roller.
