If you have marks on your drum there would be repetitive marks every 76mm.

Testimonial: "Thank you for your help. I measured the distance between the marks and found that the marks are approx. 4cm or 40 mm apart. Referring to your list, the figure closest to that is 38. That means I have marks on the Primary Charging Roller. Could you please further tell me how do I locate Primary Charging Roller and go about fixing it."
