Genuine OEM HP OfficeJet 3831 Ink and Supplies

The HP OfficeJet 3831 uses two ink positions: HP 63 black and HP 63 tri-color. HP 63XL is the larger-capacity choice for either position, so the printer's black or color message should be matched before selecting a size.

Toner Buzz carries genuine HP 63 ink as individual cartridges and black-plus-tri-color packs, with HP 63XL options included. Choose one cartridge for one low position, or a paired pack when both black and color need attention.
