In my 8070 The paper jam( scrolls freely) before the Fixing Roller and not entering the Fixing rollers.i.e the paper fold in to two and not entering the Fixing Unit. I cannot Figure it Out. Pls help me Out. I post the Picture Soon.

check the main gear on the upper fuser roller there is an indent in the inside of the gear that keeps it from spinning free on the roller you might have to take it off to see it because sometimes if you turn it by hand it turns normal but in operation it will spin free. -
Separation/Transfer corona can cause this, clean/restring/or replace the corona, to eliminate that possibility..."Once a King, always a King, but once a Knight is enough!"

I here Attach the Picture of the paper jam. Pls Note that Printed side Moves Down and it not Previously printed.
How to set the Optipum value for Transfer and seperation.
I have set TR-N1=-350
TR-N2=-350
SP-N1=200
SP-N2=150
What will be the Best Value?Comment

looks like the fuser rollers are not turning like the other guy said.if you turn the handle on the fuser do the rollers turn?Comment

copyhere , U Hit nail on the head/ had to read n' look at pic again/ single sided flip over /agree on fuser not turning_Last edited by teckat; 04-29-2010, 01:10 AM.**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

Either the tooth has broke off the ufr gear as stated(common) or the fixing motor gear is wiped(usually around 4 million)Comment

Remove covers and observe what is happening live,,, the guys may be right about the fuser,, only you can be the observer!"Once a King, always a King, but once a Knight is enough!"

The Separation and Transfer Assembly cause the Problem. When the paper crosses the Drum it moves up and hit the upper wall then scrolls. How to eliminate It. I think some potential adjustment can eleminate. but dont know what is should be adjusted. Tranfer or seperation charging?Comment

I have had the same problem because of different conditions of humidity,paper, etc and have corrected it by lowering the the transfer setting a little at a time and increasing seperation a little at a time and going back and forth. also it happens with some paper and not with other paper. Also in register paper type try some other paper types even though it is plain paper it sometimes works.Comment

u never posted jam codes ?? u never mentioned if it happens from all or some paper feed locations ? cassettes & or decks/prints and or copies. ?
Check service mode copier>option >body>tp-sp-xx (xx denotes the cassette or deck that is having the jam issue). For example, if the unit is jamming only from the right deck, then go to address tp-sp-c1. Make certain that the setting for the address is 0 (default). If the setting is for tracing paper (2) and then plain paper is run from the paper source, then jamming will result.**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

I check the Jam code it is Delay jam in PS9(I Think, Because i am not near the Machine right Now). After playing some time with Separation and tranfer Settings I reduce the paper jam, More paper Jam happens in A4R and not in A4. After Changing Separation and transfer Values white spots appear on Copies how to fix optipum value for it.Comment

u need to post the exact jam codes/ a delay code 01xx and a stationary code 02xx are worlds apart**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

If it is the corona causing it, as I have already stated, restringing the corona, or replacing it should resolve the problem. I have never adjusted the corona currents for this problem. I have seen this years ago on a pair of 8500's I had in a school system printshop. Restring till it reach's a million, and then replace after a million."Once a King, always a King, but once a Knight is enough!"
