Toner on Back of Print
There is toner on the back of the printed
sheet of paper.
1.
Clean the printer interior.
2.
Inspect the paper that is loaded in
the paper trays. Is the paper clean
and free of toner?
3.
Try printing from supported media.
4. Ensure that the loaded media
matches the front panel settings. In
some cases, switching the paper
type setting, for example from
Heavy Laser Paper
cover/Index, may improve print-
quality.
5. Run fuser cleaning pages.
6. After the fuser has been cleaned, try
setting the paper selection one type
heavier.
7. If the transfer roller or belt cleaner assembly is near the end of its life, replace
that part.
