    Re: bizhub c3300i/c4000i IU problems

    It is my belief that Konica is having a large problem with the TCR sensors. I have similar problems on a 3350. It took 4 Y IU to get a good one. And you can imagine the run around in between. The TCR sensors are not reading and reporting reality.

    This isnít usually a problem because it can be changed back but it V45 doesnít display the buttons necessary to change it and then you are stuck with an error code you canít get rid of.

    It doesnít always do it though so itís a bit of a lottery.

    We have been advised not to update to this version.

    This is in Europe though.

    Dont know now if itís the same in other regions.

    Re: bizhub c3300i/c4000i IU problems

    Maybe I understood. I think I heard something from KM. When you initialize the machine, the HDD is deactivated. The problem is that in the iSeries there is no HDD and therefore an electronic card (perhaps the ssd?) that causes the error is deactivated.

    Re: bizhub c3300i/c4000i IU problems

    I have 4 machines in field this problem.
    3 C3300i and one C3350i.
    Every machines have to high tcr state.
    3 magenta tcr high and one black tcr.
    I try to lower the tcr from 0 to -3 but not good.
    A tcr is over 10% when I print halftone the tcr is reduce to normal 7-8% but after not to many printed pages go back to over 10%.
    I will try the IU change maybe it works.
    The most important I use the G00-53 FW.

    Re: bizhub c3300i/c4000i IU problems

    Hi,

    If I could hijack this thread please.

    I'm having this exact same issue but on a C3350i so far I have replaced 2x yellow IU, 1x black & 1x cyan machine only has 12K total count.

    The machine will call for a toner customer will fit new (genuine) however the message will not clear.

    Fitting a new IU of that colour temporally resolves the issue.

    I can not see any bulletins on this issue from KM?

    I don't think this is related to your problem, but who knows. There was a new bulletin and firmware update released for a number of the i model machines the end of last week. According to the bulletin, one of the resolved items is "Possible Premature IU Failure". I don't think that is what you are dealing with here, but maybe they are very loosely related? Looking at the Firmware information PDF, there are 123 issues that are fixed by the latest release, none of them seem to specifically call out the issue you guys area having though. I've attached the bulletin, and will list the 123 fixes between this and another post because, because there are too many characters for the board to handle apparently.

    Re: bizhub c3300i/c4000i IU problems

    B5 firmware does address the high toner consumption and iu destruction issue. If its loaded on a machine with already partly destroyed iu you will still need to replace it when it fails but after that point it should be fine. The duration of agitation of the toner /dev mixture has been modified to stop incorrect readings from memory.

    There are of course other reasons for ius to fail, ie loss of drum charge and solid pages of the relevent colour but these are physical issues that you need to find and fix, not software.
    If at first you don't succeed, try the way I told you how to do it in the first place.
