Replaced pcu "magenta only" then made 300 copy,
After that I smelled that there are smoke or shock
Checked pcu seems that it's very hot from the back 'socket' and message appeared

any news?
dead machine?

By your own account, YOU did something to short-circuit the machine, and you'd like us to guess what you might have touched to cause it?
Where you might have dropped a screw? Or which wire you may have pinched?
Not going to happen

It would appear that you have replaced all the problem PCU's with all new same black units or same colour units. Have you swapped the two wires in the PCU front connector to allow the correct PCU identification signals.If you modified the drum units you should have swapped the old toner sensor and place it inside the each new PCU.

There is a PCU modified chart(PDF) somewhere in the CTN forums. Have a look at the chart for the correct wire orientation.
