Curious to see if anyone else is having issues with these fusers making a loud popping noise ? I'm going to replace my 3rd one in this machine. They last about 5-6 months. The one I have on the shelf is 302RV93065, which shows it's the last revision from Kyocera of this fuser from 2018. I can keep doing this while it's still under warranty, but it's kind of ridiculous.

Re: FK-1152 M2040dn
I've heard rumors from Kyocera techs, that they have been removing the teflon sheet and lubricating the pressure pad with high temp grease (HP sleeve grease) ... with success. I haven't tried it myself, but it sounds like you might get an opportunity.
=^..^=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.

Re: FK-1152 M2040dn
I have replaced several of these because of this issue or jamming & the only thing I found that seams to help is, setting the sleep mode extremely early, like 5 minutes or less.. This machine warms up so quick, most customers don't mind the waiting to come ready.. Setting the sleep or low power to 5 min or less also allows the drum unit more life & the fuser too.. The more heat inside the unit takes life from the drum unit.. Hope this helps
A while back, I bought a fuser rebuild kit, (fuser web cloth & replacement oil for the cloth), It is not an easy job, not hard, just have to pay attention & take your time. I only ever did one, but it hasn't had any issues since I installed it in a customer's machine. Been about 9 months since install.Comment

Re: FK-1152 M2040dn
Have had several cases like yours.
Take a look for the fuser drive and install latest FW.
Since V 2.02 KDC added additional cooling.
Corrective measures for decrease of the oil applied to the fuser sliding sheet.
The oil applied to the fuser sliding sheet might decrease after fuser overshoot repeatedly when the main unit is stopped at jam/service call error, and the fuser torque
might increase to cause the fuser jam.
You also can order complete drive unit if you don`t get separate parts.

Re: FK-1152 M2040dn
We have replaced at least 20 of those fusers (FK1150 in the UK). They are brutal. There's a bunch of bulletins about jams. You can get oil pad modification kits which seem to work okay.
The loud pop you are hearing could be a broken ratchet gear.
Have a look at the attached, it also has the sounds you may hear and the cause.

Re: FK-1152 M2040dn
Try taking apart the fuser drive asy and stretching spring #2. Worked for me, they get weak I guess. Have even put a little heaver spring in there. No more problems.Comment

Re: FK-1152 M2040dn
So, I warrantied the fuser and they didn't want it back, so I took it apart. The sliding pad was definitely "thermally expanded" as is stated in the bulletin, although that should have been fixed in the updated part. The noise I hear has to be the ratchet gear popping, from the fuser being tighter to turn. I guess I'll warranty them if that's still an option and hopefully they fix them. If not, I'll look at the drive and removing the sliding sheet.
Thanks for all the input. I appreciate you all !Comment

Re: FK-1152 M2040dn
It's the fuser drive plate as mentioned above. When the fuser gets hard to turn because of the problems discussed it wears out the gears.
Replacing the fuser is good to reduce the load but you'll get popping again if you don't replace the drive piece.
Very easy to replace the drive plate but you have to take a good look at the machine to see that.
Just order the whole thing (302RV94020 PARTS PLATE DRIVE FUSER ASSY) but here's a breakdown:
