    I'll go ahead and order a set of drums and see if that cleans it up.

    Thanks also to copier addict for the advice about running the gradation.
    Gradation doesn't have to be run in CE mode, it's also in expert mode so the office manager could actually do it. [Utility][Administrator Settings][System Settings][Expert Adjustment][Gradation]

    So here's a weird one.
    I called the office just to confirm a few things, and the manager says that it only does the lines on prints from a computer, not copies.
    How is that possible?!
    Should I still go ahead and replace the drums, or could it be something else?

    Is the copy settings defaulted to black and white? If so then they would not see a magenta line on copies. If they are printing in color then it would show up. My concern is if they are printing black and white and it still shows a magenta line then you need to default their print driver from full color to black and white.

    Morning all,
    I just wanted to thank everyone for their input and advice.
    I replaced the 3 color drums, and performed the gradation as directed.
    Print quality is back to bueno.

    As an additional note, gradation can also be run from admin mode under expert adjustment.

    Yep, that's where I ran it from, at the suggestion of someone above. Sorry, can't recall who...you know who you are.

    The 3 color drums were simply end of life.
    I replaced them and all is good. Machine prints and copies like new.
