    Toner looks melted but not adheared to the page

    I have a sharp MX-2600N that when printing Color images ends up with a spot that looks melted and not adhered. Then the next page or two will have globs of toner on them.

    I assume this is the Fuser. but I wanted to make sure there was not something else to check.

    This machine sat for several years in dry heated indoor storage.

    Sounds like the fuser to me

    If it has sat for several years there could be issues with all the consumables. I would do a total PM on the machine.

    What consumables would you recommend replacing. Is there a good source for a complete kit?

    I am noticing that this is really only happening with the pure black toner. When the printer is printing colors or almost blacks its fine. Only pure black in large deposits seem to be causing an issue.

    This only has about 69K pages on it. Mostly Black and white.

    Now I am wondering about the developers and the OPC drum.

    Looking at the fuser it seems like it would be all bad or all good. There is defiantly a roller involved as its in waves about 6" apart. But the fuser roller is heated from the outside so it should not be able to heat unevenly like that. The circumference cant be much more then 3" ether. I am really just thinking out load so I know what to search on but if anyone has insight. Apart from replacing everything as I would like to know the cause. I got this thing for free and I want to get more familiar with the operation.

    Re: Toner looks melted but not adheared to the page

    Three things come to mind:

    What paper weight are you using? Heavier media will require additional heat/time to fuse properly. There are media settings to make the fuser hotter/slower for heavier paper. 75gsm paper should fuse properly on "Plain" paper setting. Please note: poor fusing in just the center is usually caused by a media setting problem.

    Generic toner can cause fusing problems. Typically though it will affect the entire page equally.

    And yes, fuser issues will cause fusing problems. When a machine is left in storage the pressure roller tends to get a flat area. It usually does not affect fusing, but does make a loud rhythmic banging sound as the fuser rotates. Sometimes the roller will round out with use, sometimes not.

    The affect you are seeing is most often caused by incorrect media settings or moist paper. Try new paper first. =^..^=
    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.

    I have tried with 20Lb staples multipurpose. 24Lb Premium. and card stock. It is worst on the card stock. But happens on the 20Lb too. I noticed the paper curling really bad and it is fairly humid in here today so that might explain it. I set the tray to "Heavy Paper" and it seemed to fuse better.

    I Printed the auto calibration page and took a picture. Shared album - Joe Payton - Google Photos, the waves are actually how its printing. Not the camera.

    The diagonal voids though the black areas indicate dead black developer.

    If that was printed LTR, you may have a secondary transfer issue. The belt may be worn, door not completely closed, or the machine may be radically off level front to back.

    I noticed that your first image was pretty curly, another indication of moist paper.

    Ya I think the moist paper was the issue, but I think the fuser might need to be set higher/longer if possible.

    The black developer makes sense.

    What about that makes you think the transfer belt is bad?

    In your second image all colors have better fill toward one end of the stripes, and lighter fill toward the other end of the stripes. It's a very unusual coincidence to have the same image quality issue in all four imaging units separately. It's considerably more likely to have a single cause, and the only common imaging component used by all four colors is secondary transfer. =^..^=

    I have had a simular problem that looks like the dv unit take out the black dv unit and see the fault i had i could see the same bands on the MG roller or could also be a main charge problem on black.
