Ive noticed a few of the bigger 8 series machines that when you run larger jobs, like 100-200 pages jobs that eventually once the Ru warms up it starts to get some movement on the right side of the unit, then the paper starts making a different noise and soon after that it jams up in the Ru unit. I know there is a bulletin #10911 that applies to serial numbers A87JWY2105445-A87JWY2108920 but these units a well out of that range. The jam codes are 32-05, 75-42, 72-16. I placed a call with konica and they had me check all the usual suspects,which all check out fine as this is a brand new C458 and if I direct the output to tray 3 or the top of the Ru it will run till the tray is full, switch it back to the regular output tray and boom guaranteed it will jam up after the movment and paper noise starts! Anyone else notice this and when testing these please make sure you run 100-200 copies through them, Im sure customers will hate you if they have this problem and you do the basic maintenance

Re: Ru-513
We are having the same issues on the 8 series. and KM tech support and the tech pubs have not been helpful. I can use a RU-513 from the 4 series and the machine runs no jamming. Were you able to solve your issue? -
Re: Ru-513
We had the small entrance guide on the finisher warp. Once it was replaced problem went away.

Re: Ru-513
We have had the same issue. Konica rep came by and said they were working on a fix. I have removed the metal frame support on the bottom side of the ru and installed washers under the four outermost screws. the innermost screws do not add washers. when reassembled it removes the bow. also on the upper guide i install a washer underneath each screw there which increases the gap for the paper to enter. it works great. good luckComment

Any news from KM about a fix?Comment

Re: Ru-513
KM released a FOC parts on this. They put some washers in the RU unit to assist with Jamming. The codes you listed are exactly what is on the bulletin. Order some!

Re: Ru-513
It is possible to have bulletin n. 10911?
ThanksComment

Re: Ru-513
In the uk our bulletin says to cut down the higher posts so that the reinforce plate sits flat.
Seems a better solution to me.Comment

Re: Ru-513
I don't have access to this bulletin, do you put the washers under the metal frame on the bottom side?
I have seen the UK/European bulletin tech51 mentioned but in our case (C458 + FS-536SD) the base frame is flat so there is no need to cut any plastic.
We even replaced the the RU but the jamming still starts after about 100 pages.Comment

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.

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.Comment
