Repair ; printer not working | power adapter 

for your problem, the 1volt difference doesn't affect anything I guess.

Hi, on 1:36min what is the name of the part on the left side black with "4 legs"? And is it possible to buy new and replace it?. Thanks.

@@DB-dj2ol it is transformers, there are sales in the online market.

If my HP printer power supply output parameters is +30v 333mA, how i need to know wich one transformer i need to buy?. Are sure that it calls transformer because i can't found any parts online, im talking about this small black part on the bottom. Thanks for information 👍

@@DB-dj2ol Oh, you're talking about the little black, I think you're talking about the big yellow, sorry I don't know the name, I've also had damage to the little black, and it's not found in the online market, maybe it's hard to damage.
