    You need new primary corona wires
    Too bad you had to do all that work first
    Clean or replace the front filter also.

        You did not mention ETB and ETB cleaner.
        I did fight with a spot/line issue which turned out to be a broken cleaner belt in the back.
        That cleaner belt tensioner has been modified too.

        I still think it looks like primary spots
        I beg you to replace the primary wires and prove me wrong
        I get that your primary assembly is 10%. Rated for 1 million
        The wire counter is under PRDC
        They are rated for 250000.

        6000/8000 are notorious for primary spots.
        The cleaners have been modified for that issue.
        They have even suggested using ImagePress cleaners
        Primary spots have been around since NP7550

        Were the spots there before corona assemblies were replaced.
        New parts occasionally fail prematurely

        Run 50 double-sided PG 1 or 4 , and you should see those spots get gradually worse. It may even change into a black band down the middle of the page

            Replaced the primary charge corona ,dots spot disappered but one line is appearing on the front edge of the paper which is coming in feed direction of the paper
            note
            1. i supposed to inform when replaced the drum processing unit ,on time itself replaced the new ETB BELT,transfer roller,cleaning brush cleaning blade
            because DRB1 REACHES 100%(existing drb1 counter is 1%)
            2. back to the issue,after replaced pr corona ,replaced the secondary charge corona also but still line is appearing
            but the line is not appearing in list print its only appearing on copies to confirm the issue i took the auto gradation page its appearing on that page so as i observed if any toner consumption portion comes to the particular area this line visible .here i attached the copy.
            thanks for your previous suggestion and expecting your suggestion once again to close the issue
