What Ink Does the HP ENVY Inspire 7900e Use?
Last Updated:Quick answer: The HP ENVY Inspire 7900e uses HP 64 ink — one black and one tri-color cartridge — with HP 64XL (HP 64XL Black and HP 64XL Tri-Color) as the high-yield option. It does not use HP 67. HP 64XL black prints about 600 pages compared with about 200 for standard HP 64.
HP ENVY Inspire 7900e Ink Cartridges at a Glance
| Cartridge | Part Number | Color | Approx. Page Yield |
|---|---|---|---|
| HP 64 Black | N9J90AN | Black | ~200 pages |
| HP 64 Tri-Color | N9J89AN | Cyan / Magenta / Yellow | ~165 pages |
| HP 64XL Black | N9J92AN | Black | ~600 pages |
| HP 64XL Tri-Color | N9J91AN | Cyan / Magenta / Yellow | ~415 pages |
HP 64, not HP 67. This is the most common mistake with the ENVY Inspire printers. The newer ENVY 6000 and DeskJet 2700/4100 series use HP 67, but the ENVY Inspire 7900e series uses HP 64. The same HP 64 / 64XL cartridges fit the ENVY Inspire 7920e, 7955e and 7958e, the ENVY Inspire 7220e and 7255e, and the ENVY Photo 6255, 7155, 7855 and 7858.
Important — HP+ warning: The "e" in HP ENVY Inspire 7900e means it was sold for HP+. If you activated HP+ during setup, the printer is locked to Original HP cartridges for its lifetime, and compatible or remanufactured cartridges will be rejected with a "cartridge problem" or "non-HP cartridge" message. HP+ cannot be switched off after activation. If you skipped HP+ at setup, compatible cartridges work normally — see how to keep HP firmware updates from blocking your ink and our HP Instant Ink vs. compatible cartridges breakdown before you buy.
The HP ENVY Inspire 7900e is a photo-focused home all-in-one (print, scan, copy) with a 35-sheet document feeder, automatic two-sided printing and a separate photo tray, which is why ink costs add up quickly for photo printing.
Save on HP 64 / 64XL
Castle Ink's remanufactured HP 64XL Black (N9J92AN) and HP 64XL Tri-Color (N9J91AN) cost much less than genuine XL cartridges. Every cartridge is tested, backed by a 1-year guarantee, and ships free on orders over $50. For check printing we also carry HP 64XL Black MICR. Remember: compatible cartridges will only work if HP+ was not activated on your printer.

How to Replace Ink in the HP ENVY Inspire 7900e
- Turn the printer on and open the ink cartridge access door on the front of the printer. Wait for the carriage to move to the center and stop.
- Press down lightly on the cartridge you are replacing to release it, then pull it out toward you. The tri-color cartridge sits on the left, black on the right.
- Take the new cartridge out of its packaging and pull off the plastic tape by its pink or orange tab. Do not touch the copper contacts or the ink nozzles.
- Slide the cartridge into its slot at a slight upward angle, nozzles facing the printer, and push it forward until it snaps into place.
- Close the access door. The printer may print an alignment page — scan it if the control panel or HP Smart app asks you to.
Troubleshooting Tips
"Cartridge problem" right after installing new ink: First confirm you installed HP 64, not HP 67. Next, check whether HP+ is active (look for it in the HP Smart app). If HP+ is on, the printer accepts only Original HP cartridges. If not, wipe the copper contacts and reseat the cartridge.
Streaks or missing colors: Run "Clean Printheads" from the HP Smart app or the printer's Tools menu. The printhead is built into each cartridge on this printer, so if one cleaning cycle does not fix it, the cartridge itself is the likely culprit.
Low-ink warning on a brand-new printer: The cartridges that ship in the box are lower-yield setup cartridges. That early warning is normal — it is not a fault.

Bottom Line
The HP ENVY Inspire 7900e runs on HP 64, and the HP 64XL tier roughly triples the black page count. Double-check the number before you buy — HP 67 will not fit — and make sure HP+ is off before you switch to compatible cartridges.

Frequently Asked Questions
Does the HP ENVY Inspire 7900e use HP 64 or HP 67?
HP 64. HP 67 is for the ENVY 6000/6400 and DeskJet 2700/4100 series and will not fit.
Will compatible HP 64XL cartridges work in the HP ENVY Inspire 7900e?
Yes, as long as HP+ was not activated during setup. If HP+ is active, the printer only accepts Original HP cartridges.
Does using remanufactured cartridges void my warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, HP cannot void your printer warranty only because you used compatible or remanufactured cartridges. HP+ is a separate restriction you agree to during setup.
How are these page yields measured?
They are approximate figures based on HP's ISO/IEC 24711 testing. Photo printing uses far more ink than text.
