Genuine OEM HP Deskjet 3631 Ink and Supplies

The HP Deskjet 3631 uses HP 63 ink, with HP 63XL options for more pages between cartridge changes. You can choose the capacity for black and tri-color separately, so extra black ink does not mean ordering extra color ink too.

Toner Buzz carries genuine HP 63 and HP 63XL cartridges for the 3631, along with black-and-color packs. Choose a single cartridge for the ink you need, or a pack to order both together; check the black and color capacities rather than assuming a pack contains two XL cartridges.
