No. The problem is that the printer is dead completely, no sound or light
comes from it, no parts are moving, so I assume that it's the power supply
unit which failed.

Here is the board:

I found that there is no voltage on the transformer outlet marked red on
this pictu

so perhaps this transformer is faulty?

What do you think?

The transformer is marked as: Humming-V2 SW.04.20
but I cannot identify that transformer.

Would someone scrapping these printers be so kind and send me that
transformer?
