Samsung forum: Toner Cartridge MLT-D209L/XAA not working with SCX-4826FN

I have experienced the same problem as Jorge_F for now 4 brand new D209L cartridges on my 1yr 7mo old SCX-4826FN. I first bought one from TonerMax to replace the sample/demo unit. I didn't use it right away since I didn't need it when it arrived, but when I did try it, it only worked 20% of the time (4 out of 5 pages were blank), usually requiring me to take out the toner and put back in again to get it to work at all. I exchanged the the unit via Samsung and the new unit would work only for single-sided printing while the sample toner unit still prints double-sided with no problems. I got support to exchange the single-sided-only toner with another. The replacement only printed blank pages so I did an exchange for it too. The 4th toner arrived today and it too is only printing blank pages. Clearly something is wrong here! After exchanging the single-sided-only toner, and having no luck with its' replacement, I figured it had to be a printer problem. After talking with the local service center tech about getting the printer serviced, and explaining that the sample unit works fine, but all the other toners I had tried wouldn't work at all or wouldn't print double-sided; I was told to exchange the toner, again.
Do these MLT-D209L/XAA toners have this high of a failure rate? Since my printer still works with the old sample toner, is there still a possibility that the printer is the problem?

Please help!

I just got a second large toner cartridge D209L and it does not work. I had (4) D209S smaller cartridges that worked perfectly. I never had any problems with them. I put the used cartridges back in and it prints with no problem other than being a short on toner. Love the printer otherwise but this is crap if only the smaller toner works. Pay $70 for 2000 pages versus $100 for 5000 pages.....

I have the same story. I did not use much my SCX-4826FN and it is a bit more then a year sinse I got it, so I'm out of warranty. I still have original cartridge, which works fine, but shows no toner. I purchased new cartrige MLT-D209L/XAA from Amazon and I had to return it because it was jamming and printing only one side. I replaced it with another one and paid for shipping. Both did not work the same way. I called repair center and guy from repair center came to my house and stated that cartridge is bad. I sent cartridge back again. The guy from repair center ordered again MLT-D209L/XAA cartridge directly from Samsung and gues what - it did not work the same way! Now I have to pay to repair center and I paid for shipping back and force for 2 cartridges. I'm not even talking about wasted time and useless phone support from Samsung. The printer still works with original cartridge, but what a disappointment!

So after two cartridges that failed to work, numerous calls to print repair and toner shops, Samsung customer support call (rating - Epic Fail), finally decided that this thing was going to become a brick if I didn't start taking things apart. So found a really good youtube that showed you how to refill your toner cartridge. Took the toner out of the new cartridge that isn't printing and put it in the starter toner cartridge that is near empty but still prints. So now the starter toner has more toner, and its printing!! No streaks or anything. Thank God for youtube.
