For reliable performance and consistent results, choose HP original ink cartridges. Designed with the new JetIntelligence technology, these innovative cartridges utilise smaller, more robust components, as well as ColorSphere 3 toner, to improve performance and increase page yield by up to 33%. ColorSphere toner has a softer core for faster melting and smoother flow onto the page, but its harder shell reduces toner wear for longer life. Compatible with HP Color LaserJet Pro M252/MFP M277, this black toner has a page yield of up to 1,420 pages.
