What Ink Does the HP Envy 6400 Use?

Quick answer: The HP Envy 6400 series (6400e, 6455, 6455e, 6458, etc.) uses HP 67 Black and HP 67 Tri-color ink cartridges. For a much lower cost-per-page, choose the HP 67XL high-yield versions.

HP Envy 6400 Ink Cartridges at a Glance

  • HP 67 Black — ~120 pages
  • HP 67 Tri-color — ~100 pages
  • HP 67XL Black — ~240 pages

How to Replace Ink in the HP Envy 6400

  1. Turn the printer on and open the cartridge access door.
  2. Wait for the carriage to move to the access position.
  3. Press down on the old cartridge to release it and remove it.
  4. Unwrap the new cartridge and peel away the protective tape.
  5. Insert the new cartridge into the correct color slot at a slight angle and push up until you hear a click.
  6. Close the door and the printer will run an alignment page automatically.

Troubleshooting Tips

  • Cartridge not detected: Power-cycle the printer; if the error persists, wipe the copper contacts with a lint-free cloth and reseat.
  • Faded output: Run the built-in cleaning utility from the printer's embedded web server or HP Smart app.
  • Color looks off: Print an alignment page from the printer's Tools menu.

HP+ and Instant Ink Note

Many Envy 6400-series units were sold with HP+ or HP Instant Ink enrollment. HP+ printers require Original HP cartridges at activation. If you'd prefer to use third-party compatible cartridges, decline HP+ during setup or opt out of Instant Ink before installing compatible ink.

Bottom Line

The HP Envy 6400 uses HP 67 or HP 67XL cartridges. Choose the XL versions if you print more than a few pages a week, and check Castle Ink's HP 67 bundle to save significantly versus OEM pricing.
