Office managers and anyone running Lexmark CX510 printers, this remanufactured toner from Print.Save.Repeat. has been a game-changer for our printing costs! The 8,000 page yield at 5% coverage is absolutely accurate based on our usage - we've been tracking it across multiple cartridges and they consistently deliver the promised page count. The print quality is excellent - sharp, clean text and graphics that meet or exceed the original Lexmark standards. It's compatible with several CX510 models including the CX510de, CX510dhe, and CX510dthe, replacing part numbers 801XK, 80C1XK0, 800XKG, and others. What I really appreciate is that it's made and supported right here in the USA by a company that's actually ranked on the Inc. 500 Fastest-Growing Companies list, which speaks to their quality and customer service. Installation was straightforward - just pop out the old cartridge and slide this one in, same as the OEM version. We've been using these for about six months now across several printers, and we haven't had a single compatibility issue or print quality problem. The cost savings compared to buying new Lexmark cartridges is significant, especially for a busy office environment. If you're looking to reduce your printing costs without sacrificing quality or reliability, these remanufactured toners are definitely worth trying. They've become our standard replacement cartridges now, and we've been completely satisfied with both the performance and the cost savings they've delivered for our business.
