Genuine OEM HP Envy 7640 Ink and Supplies

The ENVY 7640 takes HP 62 black and tri-color ink, with HP 62XL offered in both cartridge positions. That lets you choose the larger size only where it is useful instead of buying black and color in the same size.

Toner Buzz carries genuine HP 62 ink as single cartridges and paired black-and-color packs. Match the position first, choose the size for that cartridge, and use a pack when both included supplies fit what the printer needs.
