    Well if you want it fixed then give us the info
    as for not giving you an answer if the answer from a respected TECHNICIAN on this board is not what you want to hear then quite frankly DON"T POST
    FIGURE IT OUT
    If the UI needs to be replaced then it needs to be replaced
    Not really caring if it costs 400-500 to replace that is what it is
    If you needed a kidney and it as 400-500 dollars then that is what it costs
    they do cost money
    and if you wanna be CHEAP then thats your choice but do not bash a technician who tells you what the problem is
    I am not troiubleshooting things down to component level even though I can its not how this industry works

I was looking for some pearls of wisdom regarding the C250 which might be from my missing Service Bulletins. Or, acquired by someone doing this for years on this unit. For example, in Sharp copiers, if the dev is really low or moved to one side, you'll get this type of copy quality problem and it's NOT the IU.

    Sure, replacing the Cyan IU should fix it. So will buying a new machine. Customers just love the answer about "let's start changing parts." In fact one customer told me "I don't call you guys out because all you want to do all the time is sell me parts."

    FYI, if you care to know, this problem can be caused by these types of issues:

    An IU that failed the high demand for toner - solution: Feed blank sheets
    A dirty IU - solution: clean it
    a PH Windows that's dirty - solution: clean it
    Frozen cam gear on Image Xfer Belt Unit - solution: replace ITBU
    Bad High Voltage Unit (image Transfer, Neutralizing)
    TCR malfunction (TCR Sensor) or low Vg or Vdc

    Sorry, NONE of these involve replacing the IU.

    I simply asked the wrong person. I was looking for someone that maybe had a lot of experience with this machine that could point out other things to try.

    Thanks though, I'll remember that I can just start replacing things when something goes wrong. Glad you reminded me. That's a strategy that always works. Keeps us all working too, especially in the overseas facilities where the parts are made...That's was the first poster's worry.

    Thanks for making an innocent request for contributions and some troubleshooting lore, on a technical forum, all about your opinions.
    Ok Jozef you know whats wrong or possibly wrong?

    "An IU that failed the high demand for toner - solution: Feed blank sheets" Why feed blank sheets when an auto Toner TCR will do the same without adding clicks?
    "A dirty IU - solution: clean it" Lots of luck with that.
    "a PH Windows that's dirty - solution: clean it" if it was PH window the lines would be straight from lead to trail? That ain't it!
    "Frozen cam gear on Image Xfer Belt Unit - solution: replace ITBU" Frozen gear would cause no transfer plus the belt cost more than the IU
    "Bad High Voltage Unit (image Transfer, Neutralizing)" Usually a code and not usually isolate to one iu.
    "TCR malfunction (TCR Sensor) or low Vg or Vdc" Always a code and part of the IU

    Evey thing you have told us indicates the Cyan Iu has failed! You have been given great advise, replace the Cyan Iu, If it doesn't fix it then come back and ridicule us all! But make sure you have the correct solution before you do.

    Ok, fair enough. Now, your presenting the value of your experience, precisely why I came here originally. Thanks for your feedback.

    Many of those things are recommended by Konica. And, they should be done before replacing the IU. If you don't agree with those ideas, perhaps Konica has it wrong. You might want to take that up with them, they are prescriptive for their machine.

    Seen this loads of times accross the model range. If you have an old cyan IU from any of the grey cover models (C250, C252, C300, C350, C351, C352 or C450) then you can add some of the cyan developer from the old unit into the faulty machines cyan IU. 9 times out of 10 this will get the machine going and cure the fault. But let me stress that this is a temporary fix, it probably won't last long but the extra click revenue will go towards a new Cyan IU.

    I would like to thank Pepper38_cnd and ct copier repair for their comments in support of my posts. It seems we (nearly) all agree as to the solution ...a replacment Cyan IU as the complete fix!
    Just the originator seems to have a downer on anyone who suggest it.

    I will be sure to limit my replies in future as to possible fixes if it involves any outlay of cash!!lol!

    if i am not mistaken you can go into the service modes, not sure where but look for halftone patterns. You can pick cyan, once you pick it you should get a print of that IU. The print should be a solid cyan print. If you dont get that then my friend your IU is bad and you need to replace it. You can test all your IU's like this. Test out a good one so the explanation i gave you is clearer. Good luck dude. Keep me posted.

    Problem solved

    Hi all:

    It appears we fixed this problem by installing a new Cyan Imaging Unit as suggested.

    Thanks for all the analysis and discussion.

    Thank you Jozef for closing this call, all the advice turned out to be correct.
