Original HP CF461X Toner cartridges with JetIntelligence deliver up to 33 percent more professional-quality prints, peak printing performance, and protection against counterfeits with innovative anti-fraud technology. With its durable shell and soft core, ColorSphere CF461X toner offers consistently glossy, professional-quality results and is specifically designed to keep up with the high-speed performance of HP LaserJet printers and MFPs. Despite having a more durable shell, the new CF461X toner soft core melts at a much lower temperature requiring far less heat to melt. The result is higher page yields from a more compact and energy-efficient printer.
