Based on the model it is quite possibly the fuser that is the problem. Can you post a sample? If the marks are repetitive and evenly spaced then most likely it is the fuser. A mark in the same place but randomly placed down the page is usually caused by a faulty transfer belt.

99% sure that will be fuser. The ghosting is what gives it away. That is the fuser not getting hot enough and it picks up some toner and redeposits it on the paper on the next rotation.
