Having this ongoing problem with one machine and intermittently with 2 others. All fairly low volume , less than 200k. Happens with A4 and A3 from either tray or bypass. Not so much with A4R(SEF).. Obviously it's fuser related but is there a fix other than swapping whole unit, cheers in advance.

Not necessarily fuser related ...
The question is, Is the image inside the folds or not?
Of course I've seen pin wrinkles as a result of uneven fuser pressure. It's not uncommon to have the foam roller bearings come apart, causing uneven pressure between the heat belt and the pressure roller, anywhere from 167K up to 300K. In those cases there is image inside the wrinkles.
I've also seen wrinkling caused by krinkled pre-registration mylars on the door side, machine rear. The paper is being wrinkled by the registration rollers before imaging. In those cases there is no image inside the wrinkles. =^..^=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.

Thanks for your reply blackcat, yes the image is inside the crease or fold, this is why I kind of knew it was fuser related, but i will check for those mylars in future. So what you are saying basically is that I must replace the fuser??? I was hoping for a cheaper fix!Grant me the serenity to accept the things I cannot change.Comment

If the shaft ends of the foam roller are still serviceable you can replace the bearings. It's not the easiest fuser to disassemble, but manageable. The bearings (8.25mm ID, 15.75mm OD; type 1680AH, or type 16800, or type 688ADD) are a common size used on every brand of copiers. You'll be able to identify this failure very easily. Remove the fuser and tip it a little back and forth. A couple of 1mm ball bearings will roll out onto the floor. There is an opening in the rear (drive) side cover in which you can see the affected bearing. By the time the service call comes in, usually all the ball bearings and the bearing covers are sitting in the bottom of the fuser, and it's just the inner race riding on the outer race, and a nice cloud of rust dust. =^..^=If you'd like a serious answer to your request:

you could send back to kyocera/utax under warranty,at least save some money depending on how many prints the units have clocked..Comment
