If the defect repeats down the page it is either the drum unit or fuser.
Can you measure the distance down the page between identical occurences?
94mm indicates the drum
42.7mm indicates the developer roller in the drum unit
34.3mm indicates the primary charge roller in the drum unit.
In any of the above then replace the drum unit if cleaning the drum did not 
work.
Fuser problems with this printer tend to cause defects on the back of the page.
