I have the above laser b&w printer, with the cartage MLT104S NL. (this is the correct one for this machine) 1 day as printing the paper became low and between runnings the machine stopped and I added paper. But the machine didn't restart, instead I received a message that the cartage was not compatible with the machine. It was a minute ago b/4 I added paper. I have tried to reboot the computer, turn off the printer, unplug the printer, still same notice and printer looks like its going to start but the red light reappears each time. I phoned Samsung, we tried the same things that I did earlier, no go. The man did suggest that I should but a new printer. This one wasn't expensive but it worked well. Total amount of sheet since new around 250 max.My operating system has nothing to do with it. This printer ran perfectly with xp and also now with win 8. Any help would be appreciated.
