HP DeskJet 3720 Ink Cartridges

The HP DeskJet 3720 uses HP 65 ink cartridges: one black and one tri-colour. HP now supplies these as the combined HP 63/65 cartridge, which replaces the original HP 65 and HP 65XL codes and fits the DeskJet 3720 the same way. Every option that fits the printer is on this page, and I ship them Australia-wide from partner warehouses across the country.

Which cartridges fit the DeskJet 3720

  • HP 63/65 Black (B7RT3AA), the replacement for HP 65 Black (N9K02AA)
  • HP 63/65 XL Black (B7RT5AA), the high-yield replacement for HP 65XL Black (N9K04AA)
  • HP 63/65 Colour (B7RT2AA), the replacement for HP 65 Tri-Colour (N9K01AA) and HP 65XL Tri-Colour (N9K03AA)

If your old cartridge says HP 65 or HP 65XL on the label, these are the current cartridges to buy. The XL black is the same shape as the standard black and fits the same way; it holds more ink, so you change it less often and pay less per page.
