Hi Kus, can you Imagine that I had the same issues with my Samsung laser printer?? It was a cheap model but it worked so fine and when the message of the image drum came out I just bought new toners some days before! And the drum costed more than the printer value, no way!! So I found a step by step (in my case you had to add an extra resistance to the chip) to reset the count and now it works perfectly. What a sadness, waste of time and materials and pollution made by manufacturers, that they makes billions of profits (do they really NEED to do that?). Before this model I had an HP that had the scanner integrated, and when the ink was over I couldn't use the whole device!! Just to say that it's not a Samsung problem.
Anyway you did your job against this crazyness, well done!!
