Hi, recently my prints have been coming out with two faint white lines down the pages, always in the same spot. I have tried cleaning the entire printer and so far nothing has changed.
This is the best picture I could get with my camera, the line can be seen at the right side of the picture.
Check the fuser for damage if it affects all colors.
Check the imaging unit for the specific color if it is contained to one (Print the attached pdf)
Clean the LED lenses of the affected color/colors (Check for rings on the imaging units and replace if you find one)
Usually in a case like this you will find a roller/imaging unit, or Fuser with a failed ring around them.
