Review on 🖨️ Samsung CLT-K504S Toner: High Capacity Black Toner for CLP-415NW, CLX-4195FW, SL-C1810W, SL-C1860FW by William Stevenson

I bought this for our c1810w and it has made my printer 3 times more expensive to use. I think this cartridge downloaded an update to my printer. Before installing this cartridge, I could use any type of cartridge in my printer. After installing this cartridge, my CMY cartridges suddenly became "incompatible". So now I have to throw away my current investment in semi-finished color cartridges and buy additional cartridges at 3 times the price because "Samsung" is printed on the labels. I AM VERY ANGRY.
