    Re: Operation a success! Stone removed!!!!

    I know the OEM's keep lowering the fuser temp & melting point of toner to save energy but I hope these big chunks of toner isn't happening because of it. I've never seen any of these weird toner issues until the toner shortage awhile back.

    Just went through this with a C458 in Vegas. 2 trips and a developing unit, then just developer later, I finally found and extracted the stone from the toner conveyance system.

    That thing is huge! You should add geologist to your resume after that call.

    Agreed. The only time you usually see rocks like that is when the machine's internal temperature is too hot. Did you notice that that particular rock looks like a cube? It's almost as if that rock never went through the grinder in manufacturing.


    Thanks for sharing. =^..^=

    Here's how it went down. Get a call that prints were missing Cyan. So of course I figure the usual suspect of cyan developer dumping because of overlife drum. When i got there cyan level history was 0%. After replacing cyan drum & dev unit level history was good at 6.5% so out the door I went. Few days later they call back reporting trouble code C2551 "cyan trouble". Went back and machine would not add cyan toner and level history back at 0%, vac'd out the hopper unit and when I split hopper there was the stone and reason it wasn't adding toner. I've never seen anything like it unless a copier was in extremely hot conditions and low volume. Weird because this customer is not low volume and only uses genuine Kon/Min toners. There's a first for everything.......
    some times genuine KM toner come with a lot of special code like " S " , " A "

    TN712S

    there must be some thing with the code
