Review on E-Z Ink (TM) Compatible Toner Cartridge Replacement for Samsung 105L MLT-D105L – Compatible with SCX-4623F, SCX-4623FW, ML-2525, ML-2525W, ML-2545, SCX-4623, ML-2540, SCX-4600, SF-650 – Black, 2 Pack by Mark Jefferson

Installed the first yesterday. I had to turn the printer off and on again to clear the "Incompatible" message, but after that was fixed the first few prints were dark and crisp. If the capacity is sufficient and the prints continue to look just as good, we will be very satisfied. The price was good and the instructions clear enough for my wife to complete the installation under my watchful eye. (She had never done this before and had her doubts.) Very pleased at this early stage.
