What Ink Does the HP Envy 7640 Use?
Last Updated:Last updated: September 24, 2026.
Quick answer: The HP ENVY 7640 uses HP 62 ink cartridges — one HP 62 Black and one HP 62 Tri-Color. The high-yield HP 62XL versions fit the same slots and print about three times as many black pages, which makes them the better value for most owners.
What Ink Cartridges Does the HP ENVY 7640 Take?
The ENVY 7640 e-All-in-One holds two cartridges, a black and a tri-color:
| Cartridge | Part number | Approx. yield | Castle Ink option |
|---|---|---|---|
| HP 62 Black (standard) | C2P04AN | ~200 pages | — |
| HP 62XL Black (high yield) | C2P05AN | ~600 pages | Remanufactured HP 62XL Black |
| HP 62 Tri-Color (standard) | C2P06AN | ~165 pages | — |
| HP 62XL Tri-Color (high yield) | C2P07AN | ~415 pages | Remanufactured HP 62XL Tri-Color |
Yields are ISO/IEC estimates at about 5% coverage. Castle Ink also sells a money-saving HP 62XL black + tri-color 2-pack.
What Is the Difference Between HP 62 and HP 62XL?
Same size, same fit, more ink. The 62XL Black prints about 600 pages against about 200 for the standard 62, and the 62XL Tri-Color about 415 against 165. Because the XL costs far less per page, it's the one to buy unless you print only occasionally.
Is the HP ENVY 7640 Discontinued?
Yes. HP stopped selling the ENVY 7640 new several years ago, and later ENVY Photo and ENVY Inspire models replaced it. It remains a capable printer, with auto two-sided printing, a document feeder, fax and photo printing, and HP 62 cartridges are still widely available.
What Are the Common Problems With the HP ENVY 7640?
- "Cartridge problem" or "incompatible cartridge" errors. Clean the contacts, reseat, and power-cycle. See fixing an "incompatible cartridge" message on HP printers.
- Wi-Fi dropouts. Restore network settings and reconnect through HP Smart. Our guide to printers that keep going offline helps here.
- Paper jams in the photo tray from curled or overfilled photo paper.
- Streaks or missing colors when the tri-color cartridge is drying out. Run a cleaning cycle or replace the cartridge, which also replaces the printhead.
How Do I Replace the Ink Cartridges in My HP ENVY 7640?
- With the printer on, open the cartridge access door. The carriage moves to the center.
- Press down on the old cartridge to release it and pull it out toward you.
- Remove the protective tape from the new cartridge without touching the contacts or nozzles.
- Slide it into the matching slot (Tri-Color left, Black right) until it clicks.
- Close the door and follow the on-screen alignment prompts.
Can I Use Remanufactured HP 62XL Cartridges?
Yes. Remanufactured 62XL cartridges reuse original HP shells, so they fit and communicate with the ENVY 7640 like new ones. Castle Ink's inkjet cartridges are remanufactured and backed by a 1-year satisfaction guarantee. See compatible vs remanufactured vs OEM ink.
Frequently Asked Questions
Can the ENVY 7640 print with only the black cartridge?
Yes. If the tri-color cartridge is empty or removed, the ENVY 7640 can print in single-cartridge mode using black only, at reduced quality.
Does HP 62 fit other printers?
Yes. HP 62 also fits the ENVY 5540, 5640, 5660 and 7645, and the OfficeJet 5740, 8040 and 250 Mobile.
Why does my ENVY 7640 say ink is low right after I installed a cartridge?
Standard HP 62 cartridges hold much less ink than the XL, so they report low sooner. Also make sure you installed a new cartridge and not a previously used one. Remanufactured cartridges report ink levels normally.
