Genuine OEM HP Deskjet 3730 Ink and Supplies

HP 65 is the standard-yield ink for the Deskjet 3730, while HP 65XL holds more ink for a longer stretch between changes. Because black and tri-color are separate cartridges, their capacities do not have to match.

At Toner Buzz, the genuine HP choices for the 3730 include individual HP 65 and HP 65XL cartridges, a two-pack of black ink and a pack with black and tri-color. Pick the twin-pack when black runs out most often, or the combined pack when you need both inks together.
