No problem with that cartridge completely consumed and that I advise owners of a SCX-320x. In remplacement'ai bought a compatible cartridge (from another vendor): 70% of toner remaining, the use has become impossible (traces slobbering and totally unreadable text). After removing I checked visually, this cartridge "compatible" which seems quite the same without fingerprint "SAMSUNG". If done manually rotating the drum, it "picks up" distributed toner packets randomly to each rotation. This is the second time I have problems with a toner cartridge "compatible" on a printer. While the price of a consistent is halved, but the cartridge is disposable third !!! So for me compatible cartridges: DONE!
