HP SV145A Samsung MLT-R303 Toner

well today what I'm gonna do is I'm gonna replace the toner in this samsung printer usually what I do is I just buy a brand new cartridge but I'm gonna see if I can save a little bit of money and just replace the toner and use the old cartridge this is the samsung Xpress em 28 30 DW and I'll show you how I replace the toner here's the little kit that I bought comes with the toner I bought the piercing tool this is gonna make a hole in the cartridge and once you make that hole in the cartridge you'll go ahead and just fill it up with a toner and then after that you seal it with a piece of tape it's real quick pretty easy also just be real careful with this this is this is kind of like a soldering iron and it gets super hot just be careful with that that was pretty easy very hot gotta be very careful with it now supposedly there's still some toner left in here and and by the instructions
