      How many copies are on the UFR? It should be changed at 500k. Ditto the LFR and all bearings. Check and make sure none of the drive gears have lost teeth or are cracked. Do you hear any unusual noises when the fuser is running? Is the web dry?

          UFR means upper fuser roll, LFR means lower fuser roll. Sometimes if the web goes dry there is not enough oil on the upper fuser roller and the paper sticks to it. 010B code is a delay jam of the paper leaving the fuser and can be caused by a web with not enough oil. I would still check the life on the rollers and bearings and check the gears for cracks and breaks. Good Luck.

              One thing to check out...

              I just recently saw something similiar to this, check the input drive gear on the front of the fuser on the upper roller. Mine had the lug break off, and the gear would hold about 99% of the time, but would occasionally slip and cause the roll up collision look that you pictured here.

                Hi thanks for the reply. The paper jam is happened when the paper mis feed i.e No margin in the paper. the content moved toward front(Nearly 1.5Cm front). I think some gear problem but i could not figure out which gear. Any idea about it.

                  Looks like it maybe time to replace the fixing/feeder deck.You can try to reform the ears on the holder that the bushings sit in but the best thing to do is replace the entire deck.If your image is moving up the page then your registration is the likely culprit.

                    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.

                          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?
                          Is the glass half full or half empty? I say neither. The glass is obviously full, full of potential. The potential to hold more water or the potential to quench a thirst. Life is all about how you see it.

                            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.
