Samsung SCX-4521f - Power supply repair-no power

Got this printer from dump and when I connected it, it has not powered it up. it was the faulty power supply, actually only one bad capacitor wich I had to change. I just need to clean the paper pick up roller because sometimes it happens that printer does not pick up paper. Otherwise its a great laser multifunction printer, and i like it. it can print up to 20 pages per min. Whole thing is based on Samsung Ml-1610 printer. Well I think it is :D So now for a while I have changed from Kyocera laser printers to Samsung :D
