    Re: Ru-513

    Here's the info I have on it.

    Follow the official bulletin and also the other document has you put a felt pad where the upper cover rests when closed. Do both. Someone told me the metal washers by the hinge was an old fix, I'm not sure if it has to be done or not. I just did one today (8 plastic washers on plate + the felt pad) so we shall see how it works.

    I don't see how the washers do anything though.

    Exactly my thought when we got the bulletin a few weeks ago. I don't see how this "fix" will actually do anything to remedy the jamming issue. Doesn't make sense to me.

    Re: Ru-513

    I have only dealt with this once, so my sample size is small, but I did not have any success with the washer mod outline in the bulletin. We received a new c458 and a new c558 with finishers/ru/etc a few weeks ago. Started getting this jam code right out of the box. After anywhere from 75-300 continuous pages, each machine would start to jam at RU513 entrance. Despite my RU's supposedly being in the "fixed" serial number range, I ordered the FOC washer kit. No improvement. Tried modifying the RU entrance so it had a wider entrance with moderate success, but still not good enough that I felt comfortable delivering to our customer. I put thousands and thousands of pages through these machines trying to get those goddamn RU513's to work reliably. In the end, I gave up. I dusted off two "old style" RU513's from my graveyard. I had ZERO problems after installing the "old" RU's, even though they were dirty and scratched up.

    Rumor is that the manufacturer changed the composition of the plastic, leading to excessive warping of the entrance guides.

    Somewhat related, it kinda seems like the newer 8 series runs "hot" around the fusing unit. Not sure if it is an issue with the ducting, the "quiet" fans, or just poor design, but it seems like the 8's get hotter in that area than the 4's.

    A Brand new ru513 isn't the same as from the older series this I can confirm, especially at the entrance side, it bows due to heat, I applied 4 1/16 in approx washers on the 4 corners of the metal plate at the bottom of the unit under the plate. Then screwed it all down, pulls the middle away to counter the bowing. Haven't heard back from it yet. Piss poor design imho.

    Re: Ru-513

    the injection mould was screwed up at the area of the metal reinforcement plate at the bottom side of the entrance.

    the 2 middle posts are supposed to be flush with the reinforcement ribbing and not protruding to the same height as the outer 4.

    The newly installed reinforcement plate (not used on early versions) has only holes for the screw threads for the centre 2 and not for the posts like the outer 4. It results in the entrance being bowed in at the middle and paper jamming around 100 pages onwards. The issues been known about for a couple months now.

    They made a replacement plate available for affected units or you can simply drill out the centre holes in the plate yourself (for the posts to come through the middle 2 holes like the outers). The fix is a 100% success.

    Just look at the entrance of an RU out of the box, the entrance upper and lower should be parallel, not bowed in. Its only a certain batch and has since been fixed.
    If at first you don't succeed, try the way I told you how to do it in the first place.
