    8e versus 8 series drums

    Anyone else noticing the 8e drums (DR314) fail around 50% life which isn't much more than the standard 100% life on the 8 series drums? (DR313K)

    Seems their fancy spiral cleaning roller on the PCR isnt doing much.
    If at first you don't succeed, try the way I told you how to do it in the first place.

    Yes since the introduction of the charge roller these image units don't last as long as previous units with the corona charge.

    That's what i expected, but until now i have not many experience.
    what is the meaning of "fail"? the quality is not acceptable for foto prints or black streaks on the print? are the surfaces scratched or it is blank and only the charge roller are scratched or deformed?

    I know this from kyocera printers... if the drum surfaces are ok then maybe we got the charge roller as a spare part? china/alibaba

    This is my defnition of "Failed"

    FYI, they say these drums last for 300K - I'm yet to see any changed by the customer. Like clock work around 50% the call comes in for bad print quality.

    PS. Holy crap, are we only afforded postage stamp sized attachments these days?

    Have no single one, but this drum looks like shot!
    PCR issue indeed.
    I know you probably working for KM direct and Parts are replaced per SM and only Original toners, what they said?
    Thanks for warning me on these units.

    I have never seen one reach anywhere near 300k

    From what I can tell with the charge roller running on the OPC this wears it out quicker than a corona charge which doesnt physically make contact with the drum.

    Cool Re: 8e versus 8 series drums

    My experience is 8 series drum also fail before completing its 100% life. Drum gets scratched with toner debris but customer use it to the end and also do not complaint about it. Because those steaks don't appear or clearly visible in text.

    May be i am wrong but what i diagnosed is, its due to charging roller. Whether we use OEM toner drum gets damage before life. Compatible toner destroy drum around 60 to 80K.

    While 8e series drum also fails before life. I agree.

    Re: 8e versus 8 series drums

    Yes, I confirm! Nobody has ever finished their life cycle. Once in a 308e I had a drum almost completely stuck with toner. All original consumables. The customer hadn't reported the problem and he liked the bad copies...

    Re: 8e versus 8 series drums

    My theory is the 8 series has a charge roller AND blade both putting pressure the the OPC causing wear compared to the 4 series that only has a blade causing wear on the OPC.

    The OPC is the same on the 8 & 4 series.

    Having a same issue with 2 of the 458e's failing at around 80k. The customer got compatible toners and you confirmed the exactly what happened here.
    Why KOicaMinolta shifted to Charging rollers??????
