Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm puzzled as to what to suggest, and will need to ask more about the problem:
- do the yellow stripes appear in areas of certain colors only, or in all areas, including colorless (black or gray) areas?
- do the stripes run cross-wise, or along the length of the paper?
- do they appear in black-and-white or text-only printouts?
If the stripes run cross-wise, and not in black-and-white nor in black nor gray print areas, then it could be they are a sort of irregular motion artifact. But that's not certain at this point... and all I can recommend is very generally, that we determine what color is at fault (it may not be the yellow color oddly enough, at this point) and start by removing, gently shaking swayingly, then inspecting and putting back in its place, the color that is at fault.
