    A way to decrease density of toner?

    I see this a lot with Kyocera they seem to have a really high density of toner so it ends up wrapping in the fuser or will double image on really solid halftones.

    I know you can calibrate etc but is there anything in service mode where you can say to the machine ok that's the target density but I want say 10% less so calibrate to that.

    Probably a silly question but I see it a lot in schools where they use a really solid green or red. I usually just pop the lead edge up and calibrate the machine and hope it lasts. They seem to have the density a bit too high. I could put eco mode on but that's a bit extreme I wanted kind of a middle ground between eco and normal.

    Thanks for any help.

    There is probably a SIM mode to have it calibrate less often. There is also toner saver mode than will reduce density.

    Using OEM toner you should not be getting double imaging

    Shouldn't but you do. I went to one where the black was really dense and the machine seemed to have lost its marbles did a u140 calib and recalibrated everything and it was fine after. That one was a one off I'm more talking about really dense halftones that cause fuser wraps. The manuals are really poor at describing the service modes.

    The machine are great but I'm forever going to fuser wraps from really dense half tones. Must be a way to say ok calibrate on the light side please.

    Check under system default user side for a setting

    Is there a setting that effects everything so printing and copying?

    Do you have a specific model in mind?

    You might try:
    U485: selecting a different color table
    U429: color density adjustments

    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.

    Try U464/ Target
    Decrease value and you get more solid
    Increase value and you get less solid
    After next calibration you can check if it works

    are they using 'turd party' toners?

    Genuine toners, seeing it at every school I go to pretty much if I'm really unlucky the teachers will have took chunks out the upper rollers.

    I'm doing calibrations etc so maybe that fixes it but it's mad to see the same thing daily pretty much. It's very hard to replicate as I wasn't there to see it jam but when I take the jam out it's always solid halftones causing it to wrap.

    I'll try the u464 and u429 next one I see. Wish the service manual was a bit easier to read u464 is very hard to understand what it actually does. Is u464 messing with laser power or mag charge?

    Fairly new to Kyoceras so I'm learning something every machine I see pretty much.

    are they prints or copies?

    copies require at least 3/8" white border at top of the page to keep from sticking/wrapping on the fuser roller... standard industry standards.

    this comes from not properly placing copies on the platen glass.
