Professor Color ColorCube 8570 or 8580 Ink 4 Color Set (4 Repackaged Inks with Bypass Key

Save money and get real OEM ink with Professor Color printer ink cartridges. Instead of remanufactured printer ink, these repackaged cartridges for printers are actual OEM cartridges originally manufactured for another sales channel and filled with genuine OEM ink. It's the same reliable performance, text quality, and professional imaging you expect from OEM, but without the high cost. The revolutionary invention that makes these savings possible is the Professor Color Bypass Key. A simple but effective tool that requires no modification of your machine or technical know-how to use, the Bypass Key tells your printer it's okay to use the OEM cartridge, even though the cartridge itself was not originally coded for use in North American Printers. To use, insert the Bypass Key in the ink loader slot. The hole in the key fits over the plastic guide in the slot. You'll hear a click and then just insert the replacement ink cartridge cube the way you normally would. That's it! Just use the key every time you refill ink in your printer, and enjoy saving money. These OEM printer cartridges are for use in a Xerox ColorQube 8570 or 8580 printer, and replace part # 108R00926, 108R00927, 108R00928, and 108R00929.
