This fault is by all appearances a worn black drum issue (since you're a bit unclear on this: yes drums and developing units are different).

    So did you or did you not change the black drum?

    I did look at your scan. The area of background is definitely ~3% K only. That could be because you scanned in B&W or because the problem is with the black drum. There is no way for me to distinguish.

    Keep in mind that transfer waste is more brown colored IF you do a lot of color printing. If you do all black printing the transfer waste will be mostly black. =^..^=
    Sorry, my mistake. All the drums have been changed, and the black developing unit.

    Re: C454 Printing streaks on first pages.

    Thanks for everyone's replies. After looking at it closer I am convinced this is an issue of the wiper blade not cleaning the transfer belt properly. I removed the transfer belt unit, you can clearly see some toner, and what looks like some kind of fuzz stuck between the wiper blade and the belt at the exact spots that the streaks are coming from. After I cleaned all that out and put back together it prints fine. However I let it sit overnight, the first copies out of the machine again show that streak...

    When you you replaced the transfer unit did the line return in the same place?

    I am not 100% sure. It actually disappeared for maybe 20k copies before returning.

    Re: C454 Printing streaks on first pages.

    You made 20,000 copies overnight? I think you might have the wrong equipment for your needs. =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    I just read your post. Yes, you are right, Its the cleaning blade.Transfer belt unit cleaning blade. As you have mentioned it goes after making couple of prints/copies so its transfer belt's blade not black imaging unit or fusing. Fusing streaks are a bit different. If you have replaced it with new unit then your problem is solved.
