Estudio 200 cycling power

[kuno]

I have a estudio 200 that is cycling power. Comes on and then shuts off. Have replaced the power supply. Any ideas?

Check for any shorted wires in the fuser. They become brittle at the bends.

Unfortunately it is well known issue that in 100% in my cases leads to main PWB. Yes it is quite expensive. You can try re-flash firmwares and you can achieve temporary good effect but finally you will get my conclusion!

This is usually just a bad thermister, like the previous poster said kinked wire. Most times this problem shows up after disassembling the fuser.

Thanks for the replys. I will check the wires and flash the firmware. See if that helps.
