I made it through the included toner cartridges and replaced them with High Yield toner cartridges. Since then, I've printed about 500 pages and I'm getting a "Prepare Cartridge" K for the black toner. It says it's at 10%!? I thought these 067H cartridges were supposed to get 3000 pages. Has anyone had this experience or know what I can do?
FWIW, I got the cartridges at Staples in May, so I'm fairly certain they're genuine cartridges.
