Bests & Worsts Reviews from Amazon

First, DO NOT DOWN LOAD ANY FIRMWARE UPDATE from Samsung. They prompted me to install a firmware upgrade for a "bug" in the printer copier. There has been no issue with it. All has been working fine. Until after the install. I have been buying off-label (Green Apple brand) toner/drum cartridges which save me a bit of money (not alot). I have 2 for backup. Immediately after installing the firmware upgrade, the copier will not recognize the toner. Saying "Incompatible toner cartridge installed". And will not work. I called customer service, and first they told me to uninstall the software. I said it can not be done, as it is a firmware, installed in the copier. They transferred me to a technician, who said that it has to be done by an authorized service center, and they said that since my copier is under warranty, I can bring it to a local service center to have the older firmware version 1 reinstalled. I called the facility, and asked them TWICE if this is a service they can do. They confirmed they can. I brought the printer over and left it for 4 days. Then called them. They said I'll need to buy a new toner with Samsung brand. I said that the whole reason why I brought it over is to have the firmware reinstalled, and they had confirmed it can be done. Then today, a Samsung representative called me, saying that they will not allow the old firmware to be installed, as they specifically said in the manual that only Samsung toners can be used in these machines. To me, this is scandalous, to tell owners to install an update to fix a "bug" when the bug is simply the fact that they want to BLOCK you from using non-Samsung toner and drums. This is not a warranty issue with defective equipment, but an issue that SAMSUNG does not want people to use aftermarket or non-samsung products. BAD,BAD,BAD,BAD..... I will not recommend any SAMSUNG products to anyone!
