    Kyocera 7002i thick solid black line

    This machine has been doing this off and on and will stop doing it for months and then start doing it again. It is very sporadic and usually only does it once or twice a day or usually only a couple of times a week. Kind of looks like high voltage shorting out for a second and we put a new kit in it not too long ago, it did it before and after the kit. I have attached an example of it and paper is traveling in direction of the arrow I put on the sheet, we told the customer it is hard to diagnose if it only does it a few times a week.

    so a halfstop test... is the mark on the drum?

    if no do another and let it get to the fuser.. is it there.

    diagnose from that point.

    Before doing this clean the machine completely.. also check transfer roller

    Problem with that is it only does it once a day, maybe, so we have no idea when it's good to do it. The machine has been completely cleaned when we put a brand new maintenance kit in it and it did it before and after the kit was installed. The machine night make 5 of these a week at random times of the day.

    Does it do it during the copying process or printing process or both? This looks like a copy...and if it is, is it on the glass or through the doc feed???

    replace the transfer belt, The kyocera rep that Handels Wisconsin and Illinois gave a webinar on trouble shooting with a sample like that
    and it was the transfer belt.

    Tough problem at this rate. I would think also high voltage sparked intermittently.

    P.S
    I like also your post count vs rep power and good quality scan sample

    If you look at the sample you provided, the black stripe has a margin, it does not go to the edge of the page. That tells me this is a scan issue and not a print engine problem. If it was a print engine issue it would extend to the edge of the page, since you have the margin it is caused by a scan issue. Thoroughly clean the optics. It is probably a "dust bunny" that gets in the way of the optics path on occasion. Hope this helps.

    What I scanned was a print from a PC not a copy, if it was dirt or dust in the optics the "line" would also follow the paper path not be perpendicular with it. The black "line" will appear at random places on the page but it's always about the same size.
