Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

I need to ask about this obviously 'broken' BizHub machine:

Does any error code show on the display, even briefly?

Customer: replied 1 year ago.
Hi, the display is black, it doesn`t work
Expert:  Russell H. replied 1 year ago.

That the fans (lueftern) do not work, and the display is black, seems to suggest, that the power supply is not supplying all the voltages needed for the machine to operation or start up properly.

The other possible interpretation of this is, that the central processing board of the BizHub's control circuitry, is not initializing. But having no fans really makes it more likely that the power supply is defective. Check the power supply voltages first, if possible.

(If you do not know how to check them, a Service Manual for this model of BizHub, if obtainable, would be the ideal reference to consult for that information. Do you have one? Would you be interested in obtaining one? it would help you greatly with the repair process.)
