The printer Samsung ML1510 is dead.
Here are the pictures of the electronic board:

What electronic component did fail? How can I find out that with an analog
multimeter. What is the most probable cause of failure?

The components with radiators read:
M1261S
44 L
(the smaller radiator)

Bigger radiator:
STR
G6353
45 15

Fuses seem to be ok, as well as the main switch.

Thanks for help in advance.

Samsung printers are basicly one cartridge use printers, no quality in them,
I suggest you throw this printer out and buy a HP printer.

I see nothing physically bad, and unless you know what you are doing
with electronics troubleshooting, you could cause more damage instead
of finding a problem.

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?

If that transformer is directly wired to the mains supply and has iron
laminations then it sounds like it's definitely faulty, but if it's not then
it's very unlikely to be the problem. Bear in mind that if the printer has
a switched mode supply then there won't even be a mains transformer.
