Question about Samsung SCX 4521F All-In-One Laser Printer
You shouldn't refill toners on these types of printers. They are disposable and the parts inside them are only made to last as long as the toner does.
There is a white lever on the left side of the toner that needs to be reset into it's "new" position. If you refill the toner and don't reset this lever there's no way for the printer to tell you have installed new toner.
If you do that and it still does not work, then the toner has not been refilled very well. Take it back and get it checked, or better yet go buy a new toner cartridge.
Don't forget to clean your corona wire which you are supposed to do every time you replace the toner. Look in your owners manual, or download it from Brother.com
