    It's not in the manual because it's not ment to come apart. I've had (very little luck) of using a q-tip to clean the corona's but I wouldn't recommend it as you'll get the little pieces of cotton left on the scortron. Maybe try a lint free cleaning pad that you can get in there, would be my suggestion.
    Good luck

    Color is not 4 times harder... it's 65,000 times harder. They call it "TECH MODE" for a reason. I have manual's and firmware for ya, course... you are going to have to earn it. (I'm arrogant LOL)

    Ye, I get it, but what could cause color mixing on copies, for example, if i print 10 papers with blue sign on it, on some papers it will be blue, on some green/blue, on some green etc...

    After that, open the left side door, take out the waste toner bottle and pull the transfer belt out.

    Re: C450 Corona cleaning

    Ive been tempted to insert compressed air into the slot under the coronas where the ozone is drawn out - may make a hell of a mess but i bet it would clean them good enough.

    i have dismantled and cleaned c250 imaging unit coronas when they were white banding at the edges (no developer loss) and couldn't be bothered going to get replacements. It does work but its alot of effort.

    You mean secondary corona inside machine? ( not the one's on IU) , where exactly are they located,and how to reach them? ''under the coronas where the ozone is drawn out'', i dont understand this well, picture perhaps?

    Yes, as SmellsHot said, you need to remove those screws. That's why I wrote "After that" following SmellsHot post.
