Xerox ColorQube 8870 Magenta 6 Ink Sticks Solid Ink (17,300 Pages) - 108R00951 | High-Yield Printer Cartridge for Office & Home Printing | Compatible with Xerox ColorQube 8870/8860/8850 Printers

I usually have to buy colorqube ink directly from Xerox because what I find on amazon is often misrepresented. Cubes are coded for regions and if you get the wrong region, it won't work. These cubes were for North America where I am located, so they are great for me. When buying these cubes, be sure to get the correct part number for your region.As for the colorqube 8870 printer, I have over a dozen of them. I like them because they use less power, don't have toner cartridges, and are a simple technology that allows for eco-friendly color printing on standard paper - no need for glossy paper for great print quality. I have had four service visits within the extended 3 year warranty period on all 14 printers.Ink worked, seems to not last as long as ones purchased directly from retailer.Ink worked, seems to not last as long as ones purchased directly from retailer.I buy these far too often. My office printer goes through these pretty quickly. They are not cheap, but they do last for a while. Amazon offers the best price I have seen so far. They offer all the color options plus black ink.While all the other colors worked fine, the yellow inks had a peg filled in the "H" slot which broke off. Prior to breaking off, the ColorCube still knew it wasnt genuine and wouldn't use it. Even with our usual trick of covering the sensor, no dice.Product was as described and arrived in a timely fashionProduct was as described and shipped in a timely fashionProduct was as described and arrived quicklyDoes NOT fit the 8570/8580. Very dissapointing.
