Paper Jam in IR8070

[mrfixit51]

Hi today i checked the gears there seem tobe no problem in gears. i think the problem is with the registration clutch. Is there any problem with pre Registration Clutch?

You can get the problems in the registration area from a weak/worn clutch, and also something to try is to clean and lube the plastic friction brake on the registration roller shaft. A quick way to diagnose this is to put a drop of oil on the shaft at the brake area, and see if your jamming issue abates.

Thanks i will try it and reply.

Did you fix your problem with the registration unit bushing falling out of the spot it sits (photo). I have had that and needed to reform the bracket a little on each side so there was no play in the registration front to back. If that bushing falls out it can through off the registration(no margin) and cause a 010B I think that is delay at the separation claw?

I fix by bend the claw and fix the unit that will never fall from the position but i still got the problem. But the unit is shaking a little is that the problem?

I don't see why there is so much concentration on registration when this photo clearly shows that paper is passing registration a delaying at the fixing assy. Not once did I hear say that you check that 52T gear that on the upper fixing roller or the bearings. If your getting 010B Jam Code, this code had always been associated with that gear or bearings. If the paper is skewing as it enters the fixing assy "and i mean skewing" then I would check clutches. Check the guide where the registration roller is located, try to run paper thru the registration manually. The sheets should flow thru smoothly, even if you try to slide paper thru it should hit the registation roller with no problem. If seems hard to slide paper thru, then check that guide, there should be a gap to allow paper to pass and hit the registration roller. Do you even cheat the door and watch how paper passes thru registration and the fixing ass'y?

By the looks of this problem, it looks like the fixing ass'y area is where I would be looking.

The reason i went with the reg area is because of the picture of the reg roller bushings being out of position.Not to mention that he said when it jams there is no margin on the page.Yes it does go thru the reg area but it sounds like it goes in too fast,thus no lead margin.

Guys i Clean the Transfer/Separation Unit by disassemble it. Now there was No paper jam and No margin mis feeding. But at the beginning of the copy the first paper scroll in the entrance of the Transfer/Separation Unit and jam. after removing the paper then the next paper goes smoothly.

Also i think the paper moves not fast its moving too slow. because the margin is vanished only the text appears in the Edge of the paper and the jam code is delay jam.

I have seen many 010B codes caused by the registration not being on or the separation pulling the page up and not reaching the fixing unit in time. The gear can most certainly cause the jam but there would be no issue with the lead edge or trail edge for that matter. But as most of us probably know there can be more then one problem here causing a compounded issue. My biggest problem here is I think we are losing something in the translation. I am having trouble determining what is wrong at this point. I think you need define the different problems it is having and concentrate on one problem at a time.
First I would check the obvious things. Check to see if the heat roller gear is damaged/worn, especially the tab that holds it in place. Secondly I would approach the registration issue. If the gear is broken it still doesn't explain the registration problem. Be sure the registration is due to the registration area and not a document feeder issue or a print issue. If the paper is curling into the sep or the cleaning unit you have a separation issue. If the paper is going thru flat the separation is ok. As Screwtape stated make sure the pre-registration guides have enough room between them so the paper moves smoothly thru.
You will need to watch the paper as it goes thru the image formation area. Does it lift, hesitate or shake? It might help if you started fresh explain if anything has improved and what you have done as well as what it is currently doing. Please let us know if it happens on single sided, double sided, every copy or just every few pages.

First...re-wire the transfer/sep.Then clean the underside of the transport belts...they slip. Make sure the transport vacuum fans are working.Clean the fuser entrance guide of any built up toner. Next check the upper fuser roll drive gear...the tooth on the inside of the gear breaks off all the time. Also at about 4 million prints the gears on the fixing drive motor assembly like to break. Make sure the fuser entrance guide moves properly. Pull the cover off the feeder assembly cheat the door and use a light and see whats going on as it runs!!!

Hi one of the bearing which hold two side Pre-registration roller is moved away and pre registration roller is not firmly fixed. (see the picture) .The paper mis-feeding may happened due to this. Now no more paper jam and paper mis feeding. Thanks Guys.
