Help me sir.. I have got this problem since last week and I am wasting a lot of my bond papers. Sometimes it would print just fine but most of the time paper would just jam the registration roller or came out folded and distorted from its fuser. I tried to remove the registration assembly to clean and lubricate all the bushings but i still have the problem. One thing I noticed is that the gears clutch of the roller is a little bit worn out.. Can that be the problem? THanks!

If you are jamming at the reg roller, the clutch has failed. Not the gears on it, the clutch itself. I change these all the time.The greatest enemy of knowledge isn't ignorance, it is the illusion of knowledge. Stephen Hawking -
Re: Bizhub 350 Registration roller Jam problem
Run the F-12 test print. Compare all the pages. If the image starts to track off the page, the clutch is slipping and failing. I had 300 of these in place for 6 years. Never changed a bushing, and only changed 1 reg roller, but I changed a lot of clutches. Those clutches groan a lot when they are failing. An important clue would be the meter count. The more info you post, the better the replies will be.
I have also had packing material behind the reg roller, years after it was installed. Been laying in one spot and one day get jarred and then grabs the roller. Last one rolled around behind the reg for almost 5 years before grabbing the roller and pealing it like an orange. Machine had 900,000 on it.The greatest enemy of knowledge isn't ignorance, it is the illusion of knowledge. Stephen HawkingComment

Re: Bizhub 350 Registration roller Jam problem
Thanks sir I will try the F-12, I don't have the spare clutch yet.. Reg roller looks fine and I don't really have a track about its meter, you see sir I got this machine from a friend about a year now and the meter count is at 226,234. When I'm opening its right door cover to remove paper jam, I could see the paper is not feed into the fuser rollers, looks like the reg roller is pushing the paper into the fuser and would just fold because fuser would not feed the paper.. Is there adjustment for the fuser roller tightness just like other Konicas?Comment

Re: Bizhub 350 Registration roller Jam problem
I did f-12 and prints are not out of track some of the pages were wrinkled though, but the print lines were straight. So maybe the wrinkle is done by the fuser sir? I have cleaned the reg sensor by a blower and I could see it tilting when a paper passes through it.Comment

Clean the paper guide on fusing entrance ,you can feel with your bare hands or remove IU and light the spot.Defects are simple, our mind is complicatedComment

Re: Bizhub 350 Registration roller Jam problem
Yes sir I checked the paper guide in the fusing and there's a toner buildup and its getting thick, so removed the plate and scrape it off and when i put it back the paper jam problem is gone. But after 40 pages of printing the problem came back and its building up dried toner in the paper guide of the fusing entrance again. I could also see that the back tip of the printed paper were a little bit dirty, so I guess the leaking is on the developer or drum assembly?Comment

Re: Bizhub 350 Registration roller Jam problem
You have several issues. If you scraped off the entrance plate, go back with some d-ink or cleaner that will clean it off smooth. Buy a red can of CRC electronics cleaner (under $5 at Walmart). Pack towels under reg clutch and protect your image unit (drum) from splatter. Use the spray straw to force spray under clutch's white collar and spin it, also rotate reg roller, repeat several times. I rarely have to replace that clutch since flushing it works for a long time. Let dry and return to room temp for several minutes in case of condensation. Blow out clutch with canned air before CRC, then again after using CRC to help dry it faster. If buildup on fuser ent. plate is returning that fast, and trail edge of page is dirty, you probably need a transfer roller ass'y. We change every 200k. Any jams showing in counter for separation are likely from that clutch slipping.Comment

Re: Bizhub 350 Registration roller Jam problem
I have my new transfer roller and Reg clutch now sir, and I haven't installed it yet.. How could I extend the life the transfer roller sir? And the right method of cleaning it? should dispose my old transfer roller together with its metal plate? thanksComment

Re: Bizhub 350 Registration roller Jam problem
Focus on the IU if you get toner spilled on paper in printing process,new transfer assy will not help that much.
I recommend replace the hole transfer roller after IU is remanufactured or changed because the plastic guide ends gets worn and metal frame is closer than it should be to OPC giving dirt in leading edge of the paper backside.Defects are simple, our mind is complicatedComment

Re: Bizhub 350 Registration roller Jam problem
I'd just removed the worn-out mylar on both sides of my mag roller, because I think it is touching the drum and scraping it off. I did also replaced the white spacer/collars, is it ok to just remove those mylars? I tried to fix it with a double sided tape but it wont hold.. Does that mean I should get a new Developing Unit or is there a supplier for these kind mylars with strong adhesive? And what is the purpose of those? thanks sirComment
