If the mark is persistent on each page and repetitive with very precise spacing, you need to determine which roller it's coming from. It could be coming from the transfer roller, before the fuser, the fuser itself, or the fuser pressure roller. Measure the spacing distance of the mark(s), then measure the diameter of the 3 above mnetioned rollers, multiply by pi (3.14159265) and compare the results to determine exactly which roller is causing the issue, then replace that particular roller. Hopefully it's not the fuser as you'd be better-off replacing the fuser film (main fuser roller lining). The fuser and pressure roller are a pain to source, and run abou $65+ for the pressure roller, and about $90+ for the fuser, not to mention this 2 last rollers will take about 1-1.5 hours to replace. They are not hard to replace using common tools. Don't forget to locate the printer service manual over the internet first.
