    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.
