Review on GREENBOX High Yield Toner Cartridge Set for Xerox Phaser 6510/ Workcentre 6515 Printers - 1 Black, 1 Cyan, 1 Magenta, 1 Yellow by Trey Dikici

Sometimes they work great and my print comes out fine. Other months these things fail completely and ruin my printer, so I have to cut the cost of a new printer (or more) to get the store to print my pages. I'm pretty sure it's ruining the printer as I'm on my third Xerox printer. The print always starts great and then I get continuous colored lines around the edges of the page and then the printer can no longer print that color correctly.
