Product Description
The HP C9721A remanufactured cyan toner cartridge from Castle Ink is a direct replacement for the OEM HP C9721A, built for HP LaserJet, OfficeJet, DeskJet or DesignJet office printers. It’s an economical way to keep your printer in service without paying full OEM prices, while still meeting the print-quality standards your team expects.
The C9721A is color-matched against OEM cyan, so skies, water and brand logos hold their reference values rather than drifting toward green or teal. Mixed colors like greens and purples also benefit because cyan is the dominant channel in both. Every C9721A is assembled with a fresh imaging chip (where applicable), color-balanced toner powder, then individually tested before shipping. Castle Ink backs every C9721A with a 100% satisfaction guarantee: if you aren’t happy with quality or yield, we replace or refund it.

Frequently Asked Questions
Will the C9721A void my HP printer warranty? No. Under the U.S. Magnuson-Moss Warranty Act, your printer manufacturer cannot void your warranty solely because you installed a compatible (non-OEM) cartridge.
How does print quality compare to the genuine HP C9721A? The C9721A is engineered to match the OEM cartridge’s particle size, charge profile and toner densities so day-to-day output should look essentially identical. If you ever see a difference, our satisfaction guarantee covers a free replacement or refund.
How fast will my order ship? Orders placed before 2pm ET ship the same business day from our U.S. warehouse with free standard shipping. Expedited options are available at checkout.
