    You're right, terrible idea.
    Ended up now ordering some used units entirely, because that's the only option.
    Can you help me out what to do when swapping them? Really don't want to end up with 6 units on my hands 4 of which are just dead

    Just follow the procedure in the manual, not too complicated.

    Were it me, I would label each laser unit C1, M1, Y1, K1, C2, M2, Y2, K2. As long as labor time isn't a huge issue, I would replace Y1 with Y2, M1 with M2, and run adjustments. Then see if you get any additional codes. If it's the first time for you, it'll take you 1 1/2 to 2 hours to complete. If you have to go back in, it'll be quicker.

    I personally have not experienced simultaneous multiple laser unit failures in the same machine, but I know of other techs that have.

    I have anecdotal reports of a C6000 that pulled laser codes at 3 week intervals. The tech replaced three yellow laser units (each temporarily solving the issue). On the fourth laser installation, he also installed the PRCB. His theory was that the PRCB was overdriving the mirror adjusters, jamming up the worm gear drive. =^..^=

    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.

    Quite comical thing is that's what pretty much happened in my case, if the units are open the shutter is way out of range of the sensor, various manual adjustments didn't have any affects even regardlessly was it made by the copying of the working unit positioning or simply making a thread that holds the shutter longer or shrorter depends on which side it was moving to. Speaking of the PRCB theory, was he wright eventually?

    Update on the whole situation, tomorrow the used one working prcb will arrive and my concerenes are about the firmware version of it. Didn't find any info on how to update it, except that it needs to be done if they're not the same.
    ┐('~`;)┌ no idea what to do on that, basically when do i get the fw or how to upload that

    It's been a really long time since I did firmware on a C6000.

    Like any of the Konica based devices, the folder structure is very important. So when you extract the machine firmware you'll have the basic folder structure, but none of the accessory firmwares. You'll have to download each accessory firmware separately and place it in the correct lettered folder, like the manual says. You'll want only the most recent firmware in each folder (not multiple versions).

    The firmware I have is at least 12 years old, so it won't help you. Follow the instructions in the manual. =^..^=

    So finally it's solved. replacing the prcb and 2 write units but now that thing works.
    Although now doing duplex top to botom even if the file is top to top for sure but i guess that's another story
