    Kyocera TaskALFA 300CI Cyan, Yellow, & Magenta Spots

    Hi Folks,

    Got a Kyocera TaskALFA 300CI with magenta, cyan, & yellow spots on prints, happens on color prints only. (See attached pics) Pulled the drums out, cleaned & coated them along with the wiper and PCR, no changes. Popped a new developer no changes. ITB is worn but not seeing anything obviously wrong.

    I'm about to replaced the drum unit, wanted to see if anyone's had this issue on this model? The service manual doesn't seem to be thorough in CQ troubleshooting.

    Let me know what you guys think.
    Thanks!

    I have the same problem with the same printer.
    A bit less magenta dots and a bit more cyan dots.

    With TASKalfa 2550ci I enable "Drum Aging" in U100 but 250ci/300ci haven't this option...
    Maybe setting AC or DC BIAS in U100. If possible I don't want to change YMC drums, they are expensive.

    Thanks in advance,
    Carlo

    Sorry to say it is arc marks on the drum that are not visible to the eye. ASi drums do not show visible faults for the most part. So note what colors the spots are, and order those drums.

    If you look closely enough you will see that there is a pattern that repeats at 96.75mm. =^..^=
    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.

    Blackcat thanks!

    Looks like my boss has drums coming in soon, not cheap.

    I havent connected PCRs to arcing on drums before, is that comon on these model? Any way to prevent that in the future?

    Also would a firmware update help as well? I think these are on version 6.


    Thanks again,

    Re: Kyocera TaskALFA 300CI Cyan, Yellow, & Magenta Spots

    The arcing is more common on low volume machines. There isn't anything that you can do preventatively (excepting making more copies and prints). The firmware update won't do anything for that, either. That's the drawback on ASi drums. They'll last 300K at high volume, and will start to arc at lower volumes.

    Be sure to do the color calibrations listed on the sheet in the drum box. =^..^=

    Re: Kyocera TaskALFA 300CI Cyan, Yellow, & Magenta Spots

    blackcat is correct. This is arcing on the ASi drums and they do need to be replaced.

    Back a few years ago, Kyocera-Mita rolled out a new lineup of "ECOSYS" copiers that designed to be environmentally friendly because the drums and toners last much longer. (They probably also did this to corner the market on the drums which is why it's impossible to find aftermarket drums for these machines)

    The 300ci is part of that lineup.

    Bad news is the drums need to be replaced, good news is they will last a long time when you do!

    All three Cyan, Yellow, & Magenta drums where replaced, cleared up all the dots and spots!

    Thanks again Blackcat for your time and guidance! And yes Taggerung we didn't find any aftermarket drums, only toner. I'm used to seeing Amorphous Silicon drums in higher yield machines that use coronas.

    BlackCat, found this blocking my K toner supply, any suggestions?!?!?!?!



    Warm Regards,

    Is this Cupcake Wars?!:

    It looks like someone dropped some "Rainbow Sprinkles" in your MFP!



    PS--not sure about it, but since the drums are "shot" I'd chance giving them a polish coating of NuFinish silicone based car polish to see how they run!...just for the heck of it!

    I have this issue many times and I thought that the reason is non OEM toner! It happens with the originals too? Every time I must replaced drums before 50K.

    And where exactly arcing come from in this case? What is the culprit? Power supply? transfer belt? DC?.....
