Bizhub C250i Fuser noise

[mojorolla]

Hi guys, I have a bizhub C250i installed 1 year ago. This printer is only 30k and started making weird noises from the fusing unit.
After printing, there is a creaking metal noise for 2-3 seconds. Has anything like this ever happened to you?
I will order a new fuser but maybe someone knows a possible cause. It sounds like the classic bearing noise.
Thanks!

Sounds like the pressure release system from your description. If you run this is service mode, does it make the same noise...?

I swapped the unit between two machines and stopped making noise .

This sounds like the classic fuser bearing noise that I've been hearing from everything from the -8 series forward. I usually disassemble and lube the bearings with something called Krytox from DuPont. Quiets them right down. I had one machine with only 10K do this on an -8 series machine.
