TLDR; It works, highly recommend. I recently bought a Xerox 6510 printer through Amazon because at their current prices they STEAL. Apparently this is because Xerox charges crazy prices for their branded toner. Normally I would gladly pay a company that makes great devices, but their prices are unreasonable in my opinion. FUD stories distributed by printer manufacturers. Add to that the fact that Xerox claims their toner is PANTONE compliant, and that makes them wary of risking cheap toner. I decided to take this risk because it's so much cheaper and allows the printer to be a self-sacrificing test mule. If it breaks, "Well." It doesn't. A while. I will update this if it changes. However, the results so far are VERY PROMISING. I've only replaced one (cyan) so far, but the printer accepts the cartridge and the colors are the same. So far I don't see a single disadvantage, only pluses when buying this toner brand. This brings the price per page down to approximately $0.024, compared to $0.18 for Xerox-branded toner. At this rate, I can buy a brand new printer every 1,000 pages and still come out on top.
