    Re: Bizhub C6500 Error code C-4520

    I had an old 6500 that had this code.

    Did everything you have done but was still no good.

    Then I found out you could suppress the code by setting a dip switch ( canít remember which one. Sorry).

    The machine ran the last year of its contract like this with no issue with colour registration.

    And before anyone asks, it was in a print shop with a particularly fussy operator so any issues would have shown up quite quickly.

    Exact. Dipsw 25-3 to ON. However, my goal is to solve the problem. With this key enabled, you would not perform the self-tuning periodically. The goal now is normal functioning and discovering the cause while I have time.

    But I appreciate your help.

    Fair enough. I admire your persistence on such an old piece of kit.

    The c6500 is long gone on my area but I do appreciate other parts of the world still have to deal with them.

    I wish you the best of luck with it.

    Here in Brazil we already have Accurio 3070, but Bizhub C6500 was not commercialized in Brazil. We import enough equipment like this and put it on the field here. With the political and economic crisis that we are experiencing, many clients still have not shown the courage to renovate their graphic park.


    With this, we still find many printers working.


    I, persistent in solving defects, still have time to fight against this 4520. If my time runs out, I will have to offer another resource.

    I think at this point, I would dig into the drum drive. I've cleaned these gears to keep them running smooth. May be they are worn?
    How many total prints on these machines?
    Have you tried the manual registration program? At least have a look at the prints from that program to see if thing are really off.

    Just a thought

    Total counter - 1,500K
    Kit 200K - 60k (43%)
    Drum's - 60K (45%)
    Developer's -60K (45%)
    Charge Coronas - 60K (72%)


    Ran the Color Registration Manual and finished OK.


    Although, I believe this setting is for copying only.
    In this case, the client is only printing. Do not copy.


    On the C6500P, this setting is not available.

    I have had to use the "Recall standard Data" from time to time also.
    Please keep us informed. I still have a couple of these out there also.

    Okay. Notice when you solve.

    In fact, the plates were all changed.
    OACB-IPB-PRCB-DCPS1-DCPS2- IC Unit- Firmware.


    I also mounted these same parts on another C6500, to discard possibilities of some wire or connector.


    It's going to be difficult, but I'm going to try to convince the customer to change the 100k, 200k, drums and developers kit.


    Any news, notice here.


    Thank you all.

    Good morning everyone. I will close this request for help. The customer decided to change equipment after requesting the PM kits.


    Thank you all for your help. This forum is awesome!

    Hopefully you didn't get stuck with an armload of obsolete parts. But its a good thing to get that old beast out of the field. =^..^=
    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.
