    what is the distance between dots? have you looked in the manual for the defect ruler?

    did you try pulling the drum and looking for a spot on it?

    Print the counter page then look for those dots. If the dots are repeating on the same measurement, then you have a problem on your drum. If the counter is above 60k from the last replacement, then you have to replace it together with the developer, blade and charge roller/brush.

    Aye! Cut the crap

    Drum spots are a symptom of trying to go too far between PCU PM. Usually start to show up at the outer edges of the drum at about 75K. Trying anything other than PM with a new drum will only make it worse.

    Time to call a tech to service your machine.

    Yeah, I believe its a drum problem. Its more than 60K copies. I thought I can still do something to extend more.

    If the same measurement of the distance of the dots (only drum replacement?).
    If 60k above copies - replace all PCU unit?
