InkOwl Laser Toner Refill Kit Replacement for Samsung CLT-K406S (Black, 1-Pack, with Reset chip)

Did this work? Yes. But I won't buy this (or the color) again for the Samsung C410W. I've used InkOwl in the past for a different printer and it worked well for that one. Unfortunately for the C410W I couldn't get the plug out per the instructions so I had to just keep drilling holes (like it said to do) and pour the toner through those holes. Unfortunately during the process of drilling/pulling/cutting I think I scuffed up my roller and now when I print I have a black spot that shows up in the print every inch or so. I'm hoping that it goes away and its not the scuff but I suspect it'll be there until I through it out, which may be soon if this keeps up.I hate to ding InkOwl for this because their product did work but they should really give a rating for how hard/messy the process will be. This one (C410W) is pretty tough to do and its extremely messy (thankfully I did it in my garage).
