Pages coming out with faint streaks or a grey band down the side? That's your drum, not your toner. The Lexmark W850H22G imaging drum unit is the part that actually transfers the image onto the page. Swap it in and those ghost lines disappear. It's a separate component from the toner cartridge — you don't need to replace both at once
