    Take the drum apart and clean the grid. If that doesn't do it you will likely need to replace the dev unit. Check life counts and replace any drums that are over yield.

    it looks like drum issue to me.

    i take it the paper feed is LEF... have you tried running it SEF that should remove remove the defect from the print.

    what are the page counts on drum/dev... also take a look at the ITB for a like smear. Do a stop test to see if it's on he belt

    Developer and drum are in contact for some reason. Check DU and UI
    Nothing like day after day

    This isn't right image to post. We need separation go in SM and print CMYK halftones. Then if all 4 colors are affected it's ITB. If only single color is affected you will know where to start.
    A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

    Blessed are they who can laugh at themselves, for they shall never cease to be amused.

    Wait a minute, this is a booklet; it can only SEF.
