Hi, On another Samsung model (ML1610), I tried shaking the toner cartridge left & right (presumably to evenly distribute the powder inside). On another instance, it was caused by a replacement cartridge (not original) and then again was when I tried simply refilling the old original cartridge. In all cases, the drum (which was inside the cartridge assembly)had to be cleaned, or the cartridge replaced (with original). The most tedious was when I had to open the cartridge and remove the replacement toner that has formed into solid lumps. Hope this be of some help. Pls post again how things turn up. Good luck and kind regards.
