I'm having some issues with this 1250p fuser module. It appears the upper separating claws are catching on the upper fuser rollers and causing some large rips to the surface. The claws are brand new and the spring mechanisms holding them are also pretty new as well. My thoughts are that thicker paper 90-120gsm prints are stressing the bearings on the rollers or something and causing the claws to catch. Seems jams are also involved with the damage. But I'm not very sure. Anyone have any ideas? I'd like to get it fixed before I put on another roller. The one in the pictures isn't even a week old now since the previous one did the same thing.

I would look closely at the following items, all to do with media type:
Is the paper size programmed accurately?
Is the media type set correctly?
Are you seeing excessive paper curl/moisture?
Is your customer printing heavy fill images with minimal page voids?
If possible dig any jams out of the trash to examine.
I believe there is a behavior factor that you've need to tease out. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

You said that the holders that hold the claws are pretty new, they do sometimes tend to stick. Try pulling back on each one and make sure that they move freely. I have started putting heat grease on the slide points of those holders. But make sure you check all that blackcat4866 said as wellComment

From what I've seen the users have been programming the size and type correctly. We live in a normally dry climate that is currently in it's rainy season. We usually get a bunch of jams this time of year due to changing humidity levels. The images we're printing are low fill mainly and sometimes it's only a few letters.Comment

You should print the Management Report. It will show every jam code, time, & date.If you'd like a serious answer to your request:

If I remember correctly it about 28 pages, and the jams start somewhere around page 23.If you'd like a serious answer to your request:

I think the 29th is when the damage occurred.Comment

English is not good enough, so I will write it with a translator.
When the paper jams, it will fold like an accordion inside the fuser unit.
The accordion paper presses the separation claw against the roller.
If you turn the roller without removing the paper, the separation claw will damage the roller.
When a jam occurs, open the adu and do not remove the paper from the transfer belt side.
You need to open the decurl unit and open the fuser exit side to remove the paper. You may need to use a knife to cut the paper between the decurl unit and the fuser exit side.
extreme cases, you can also remove the separation claw. My business partner used 200-250gsm paper, and the fuser roller was always damaged when the paper jammed. The solution was to adjust the temperature of the fuser roller to adjust the curl of the paper, and remove the separation claw and use it.
In my business partner's case, the paper was very thick, so I think it was unavoidable damage.
In your case, the paper is not very thick. I think the problem will be solved if you change the order of paper removal.Comment

No problem I definitely think you're onto something there. But I'm not entirely sure due to the shape of the marks made on the roller. It seems like they are appearing from the roller turning while in operation and not because of reversing it while pulling paper out of a jam. The tip of the claw digs in and slowly releases in accordance to the direction of running roller. Since first posting I've ran some prints of unimportant things to see what's happened. The roller has received more marks with no jams. Which makes me think it might be a moisture issue for the thicker paper.

In situations like this I'll tag all the jams that match in my database, and track those down first. Here is that list:
Misfeed J7229. Begins jamming 5000 pages into the copy job. Finisher exit sensor PS10 is dusty. Clean finisher entrance sensor PS1 and finisher exit sensor PS10.
Misfeeds J1712 from tray #4. Doublefeed code. Make sure that the side guides are snugly up to the paper. May need custom adjustment of the Air-Blow Assist based on paper size and media type.
Misfeed J1401, J1402, with increasing frequency. Up until now, feed and separation rollers have been changed twice as often as pickup. Failure of the pickup roller in tray #4. Replace pickup roller with other rollers (A4EU R715 00, [2] A4EU R714 00).
Misfeeds J1701, J3111. Separation mylar rips, entangling in the separation drive. Remove the separation mylar.
Misfeeds J1702, J3111, J7222, from tray #3. Ream of paper with mashed corner is loaded to tray #3. If the bad corner is at the leading edge, jams J1702, J3111 leaving the paper tray. If the bad corner is at the trailing edge, jams J7222 in the finisher. Remove damaged paper.
Misfeeds J3101, J3102, J3203, J3111. Telfon has peeled on the heat roller at 2.2M since last replacement. Rebuild fuser unit.
Misfeeds J1702, J3111, J7222, from tray #3. Ream of paper with mashed corner is loaded to tray #3. If the bad corner is at the leading edge, jams J1702, J3111 leaving the paper tray. If the bad corner is at the trailing edge, jams J7222 in the finisher. Remove damaged paper.
The J-7577 codes all relate to the bundle sensor jams in the booklet maker PS14. My guess is a that it is a consequence of the printed paper skewed or flipped corner as a result of you fuser damage. The booklet maker is further down the line, and unlikely to cause a damaging jam in the fuser.If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.

I gave up on the semi rigid UFR's on those years ago. ARC Services has a good aftermarket hard teflon roller that lasts much longer than the OEMS. Have never experienced any quality issues in using the either.Comment
