I wanted to replace the fuser in this 8100 DN because of noise...the new fuser gave me a c 6030 old fuser works fine, I put another new fuser in and also upgraded the firmware and this fuser gave me a c 6030. I can install the original fuser and it works just fine. thanks in advance for any ideas

I would try these new fusers on another machine, if possible. I did get a bad fuser out of the box once, I wouldn't think two would be bad. Are these fusers the right ones?

I do not have another machine to try these on and checked the part number with kyocera and another tech

Pull the connector side of the fuser apart and check the pins on the double male connector. I Have had several where the pins were pushed thru and not making contact on both sides. Specifically the 3 pin connector.

Gazoo i just checked the connectors and they are fine

Just a update, i went in service mode and somewhat reset fuser code sim 163.1...it gave me a value of 20 whatever that means i did it a few times and it is working now
