What Ink Does the HP Envy 7640 Use?

by William Elward Last Updated:

Quick answer: The HP Envy 7640 uses HP 62 Black and HP 62 Tri-color ink cartridges. For better value, pick the HP 62XL high-yield versions.

HP Envy 7640 Ink Cartridges at a Glance

  • HP 62 Black — ~200 pages
  • HP 62 Tri-color — ~165 pages
  • HP 62XL Black — ~600 pages
  • HP 62XL Tri-color — ~415 pages

The Envy 7640 e-All-in-One uses two cartridges — one black and one tri-color. Both standard and XL versions fit the printer, and you can mix and match (for example, a 62XL black with a standard 62 tri-color).

How to Replace Ink in the HP Envy 7640

  1. Power the printer on and open the cartridge access door.
  2. Wait for the carriage to move to the center and stop.
  3. Press down on the old cartridge to release it, then pull it straight out.
  4. Unwrap the new cartridge and peel away the protective tape (avoid the copper contacts).
  5. Slide the cartridge into the matching color slot and push up until it clicks.
  6. Close the door and let the printer run an alignment page.

Troubleshooting Tips

  • Cartridge error after install: Reseat the cartridge and gently wipe the copper contacts with a lint-free cloth.
  • Streaky or missing colors: Run the cleaning utility from the HP Smart app or the printer's front-panel menu.
  • Low-ink warning on a new cartridge: This is cosmetic and will clear after the chip catches up — print quality is unaffected.
