    Re: 400ci, no error code, no output with black toner

    @blackcat4866: You were 100% right: I will try to fix it somehow.

    Re: 400ci, no error code, no output with black toner

    Excuse my additional question- I am just an electronics engineer. I do not get it how this mechanical construction should work reliably with the parts I have found in my 400ci (frictional connection). Is there still a part missing?- I have the parts 1 to 3 (see the attached picture). I am missing a part for the linkage to the axis.

    I am missing something like a grub screw/ split pin to allow the spring deflection of the part with Nr. 3.

    Re: 400ci, no error code, no output with black toner

    I would like to thank everybody for the hints.- My 400Ci is working perfectly again!

    ;-)

    I could not find the missing split pin in the machine. For this reason I made a new one and assembled everything again. The printer is just running again.

    I want to thank everyone!

    Re: 400ci, no error code, no output with black toner

    You are exactly correct. In the photo you are missing a solid pin. The ring keeps the pin retained. In actuality a roll pin that fits tightly would be even better, making the ring redundant.

    As you already discovered, it takes quite a bit of disassembly to remove the main drive unit. Congratulations on your ability to get it all apart, and back together, and remembering all the connectors. That was a very difficult repair. =^..^=
    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.

    @blackcat4866:
    Fortunately I had taken some photos before I started with the disassembly.- T
    o be honest, this was quite helpful at the end ;-)

    Seriously, many experienced techs can't do that job correctly

    I'm impressed, like Blackcat said, that wasn't an easy one. Good job with the camera, I wish half the techs I worked with were as resourceful.

    Error C7902 – Drum C Error, replace Drum Unit
    => The drive coupling is loose based on their report.

    It seems that there is no chance to repair the printer with reasonable cost effort. I got a quote for the repair of USD3'235.26.- at the actual exchange rate.

    It is just a pity because the page count for the bw and color pages is in the 80k's.

    However thank you all for the suggestions.
    Its never a pity with this generation of machines.

    Drums and dev would show defect sub 50k, when rated 150k.warranty only covers you once.
    Fuser doesnt last 150k.kyocers had assumed all their machines uses 1 min to lower power setting.

    I see one i scream upgrade

    Do not get Taskalfa with 255c(board failure, $1200),250ci, 300ci, 500ci, 552ci. Even if you're paid to get one.

    Still surprised no class action against these machines.
    Idling colour developers are not healthy developers.
