Toner does not last long. Cost of these toners are too high to have to replace them every 3 to 4 months. My other laser printer toner lasted several years but of course printer died and they dont make them any longer.
I bought this cartridge jus last week , my previous cartridge lasting us almost a year. Laser Jet printers are the way to go as the toner last a long while and does not smear.
Old color cartridges were leaking, streaking color on paper. So far, these are streaking a bit but much less. On the down side, they seem too expensive.
