    Four factors come to mind when considering the efficacy of 'compatible' toners in Kyocera machines:

    1) Particle size: Kyocera has continually reduced the average particle size in the toner for more complete fill using less toner. All the engineering from cleaning to bias voltages etc are designed around this toner.
    Aftermarket toners need to ensure a small particle size, and small variance in the sizes of those particles.

    2) Additives: Kyocera includes additives designed to prevent drum fogging (ASi machines in particular)

    3) Carrier: As previously pointed out, many Kyocera devices use pre-mixed carrier in their toner so the balance of the supply mix is crucial.

    4) Fusing temps: All of the above can lead to fusing problems and add to that whether the 'compatible' has a good melt-point.


    The real question is:
    Whatever the problem you might have, is it worth it to risk it? Are the potential risks problematic for you?
    Cost of extra service call
    Cost of damaged reputation
    VS.
    Cost of billing customer for toner which, if you have a problem, someone else has to deal with (OEM)?

    Toner inclusive or not, you are always billing for toner. Whether your customer gets to choose is up to you under a service contract.

    For large accounts with cheap printers on Managed Services it can make sense to use aftermarket stuff. For that one-off you'd have to make a special trip for or complains alot...not so much.

    I can imagine it changes with each customer.

    Compatible toners are simply not worth the saving.

    It WILL shorten your drums life period.

    And you know this how? Have you spent the time to test every toner out there? Doubtful. In my experience (I was in the aftermarket toner business for over a decade), most techs or endusers try a couple of different brands and have a bad experience and assume that all aren't worth it.

    I know for a fact tht there's good toner out there because I've spent the time to test them. I had a test machine for every brand that I rebuilt and ran so many pages thru these machines. I wouldn't paint with such a broad brush unless you can say that you've tested all (or most) of the aftermarket toner.


    Now with that said, everyone should stay away from aftermarket toner if you're not willing to do your own testing.

    I've heard all this stuff from techs before. I know better.
    Embrace the process, not the outcome.

    Just a little side note:

    If you've ever seen chemically grown toner produced by HP, it's pretty amazing. The reason that it's chemically grown is because the particles are much smaller than can be produced by grinding the toner or pulverizing it. The size of the particles are also much more consistent because they have better control by growing it.

    If you put it in a bottle, it looks like liquid. That's how fine it is. The particles don't get any smaller than that. I don't care what brand it is.


    Anyway, some of the aftermarket companies invested millions of dollars in the technology to reproduce this toner. My old company rebuilt thousands of these cartriedges over the years and sold them to places like Stennis Space Center (NASA) because they wouldn't buy anything but remans.

    If you used bad toner, the chances are that it trashed the DV unit. I'd try running all the toner out of the DV units to see if that clears it up. Clean the drums. If that doesn't work, you'll have to replace them.

    Are you a tech or end user?

    Replace the dev unit, toner, and clean the machine well and the machine will be fine.

    I know this may sound a little underhanded but when a model goes out of production, I have no problem running aftermarket toner in those machines. When it starts to make copy/print quality problems, it is an opportunity to talk to the customer about for an upgrade. Even if its an newer used model.

    Agree or not, this strategy has served me well.

    Re: Kyocera Printers and Katun Toner - What are your experiences?

    I've replaced the drum now with a new one (but same old dv box with katun toner). Seems smearing has disappeared.
    I'm really not sure if it's the toner or was the drum really worn out.
    Drum has has lasted 390 000 pages.
    Is there a possibility to reset the drum counter now. So that the printer won't display "maintenance" at 500 000 pages?
    Thank you.

    Katun is very overpriced for third party toners. I used them years ago for Panasonic machines but I have never been impressed with their overpriced products. They do have a good offering of tools and bags though.
    We use ACM compatibles for our Kyocera printers and, thus far, they have been spectacular. Dirt cheap, reliable and always in stock.
    I always get samples before purchasing third party toners. If they claim they are so wonderful for the price, have them send you some samples for testing. If they won't, don't buy from them.


    Failing to plan is planning to fail!!!

    What you can try to do to clear up the copies from generic toner is to put OEM toner in and run 50 or more sky shots to run out the generic toner.
