Toner being deposited on back of page

point check

1.Hallo your rollers are dirty and smudged

2.Is your fuser unit O.k (clean)

3.is your paper good quality or are you using coated paper the wrong side? thereby staining the fuser unit (the hot part of the printer)

4. Most unlikely but have u ever turned your printer upside down??? or excess sideways tilt thereby releasing waste toner from the bottom of the printer to the roof then to your paper???

if all is nay then remove all toners and give your machine a gool blowout
