    Re: Why do 2 of my machines have ORANGE toner?

    Is developer not rust already?
    Can Fe3O4(black) turn to Fe2O3(red) I am no chemist but isn't that called reduction not oxidation?
    Whatever

    Yea I am wrong black rust is lighter than red rust so yes oxidation will turn black rust into red rust. I can still be wrong. You will need a lot of heat to go from red to black. Could then just need oxygen and water to go from black to red. Use to make black rust by burning red rust with a cutting torch to make a better burning thermite. Wonder how that will happen in that environment. But that is developer not toner.

    Then there is this stuff - Yellow Rust. Iron oxide-hydroxide FeO(OH)H2O
    Whatever

Like the spilled toner on the inside surface of the door will have more exposure to the elements than toner inside of a bottle/tank/etc that is constantly replenished and agitated. That's the best theory I've got, at least. Very open to hearing other takes on this.

    One thing is that Toner itself is a inert plastic powder How would plastic react with something else. Yes there is surface treatments on the toner for flow and cleaning aids, etc. Just curious of the environment they are in.

    If all else fails read the Service Manual!

    If that fails, meet me at the pub and we will discuss it, maybe, probably not we are at the pub!

    Never seen orange Toners. If this exist, it would be nice for all the Dutch people Could it be an early April Fool's joke?

    Looks kind of like waste toner, perhaps somebody tried something there.
    Never seen signs of oxidation at the toner slot but you can check with a magnet of course if that stuff reacs.

    I would imagine that waste toner would appear as milk-chocolate brown. If a person were to manually mix about 10% magenta with 48% yellow and pour it into a toner cartridge, it would look like that.

    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.
