HP Envy Pro 6420 Ink Cartridges
Your HP Envy Pro 6420 uses the 67 / 67XL / 67XXL cartridge series, featuring a dual-cartridge setup with one black and one combined tri-colour ink. We have been supplying reliable consumables for this printer since Apr 2020, helping home office users manage daily print tasks efficiently. Because the tri-colour cartridge contains three distinct inks, uneven colour usage may require replacing the whole unit early if one shade runs out first. Our 4.8 Google rating is built on dependable cartridge performance and uncompromising product quality.
Expected page output and replacement cycles
Page yields for the 67 ink series are calculated based on the international ISO/IEC 24711 standard for inkjet printing. Actual page numbers vary depending on text coverage, layout complexity, and photographic elements.

Choosing between genuine and compatible options
If you want to manage your printing costs, choosing between genuine and compatible options offers distinct advantages. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. You can read a thorough comparison on our genuine vs compatible cartridges to decide which option matches your specific document layout requirements.
Choosing the right cartridge setup
If you print mainly text documents, a standard black cartridge or high-yield black XL and XXL options keep your text clear and crisp. If you print photos or colour graphics, opting for high-yield 67XL variants is ideal to match the ink demands of colourful imagery. If you choose our compatible options due to price, rest assured that they are backed by a money-back guarantee. For details on how we protect your purchase, view our returns policy.

Pro Tip
Because the HP 67 tri-colour cartridge integrates the printhead into the cartridge itself, replacing the cartridge completely refreshes the physical firing mechanism. This design makes it critical to leave expired cartridges inside the printer until you are ready to slide a new one in, preventing the delicate print mechanism from drying out.
Frequently Asked Questions
Can I use a 67XXL black cartridge with a standard 67 colour cartridge?
Yes, your printer accommodates different yield capacities simultaneously. You can mix and match standard, XL, and XXL sizes within the same cartridge carriage without encountering physical fit or software recognition issues.
Why does my tri-colour cartridge register as empty when I can still print in yellow?
The tri-colour cartridge contains separate internal wells for cyan, magenta, and yellow. When any single ink chamber is completely depleted, the printer requires a full cartridge replacement to protect the printhead mechanism, even if the remaining colours have residual ink.
How does document type affect the balance between black and colour cartridge depletion?
Standard text documents draw ink exclusively from the black cartridge, while images and graphics deplete the tri-colour cartridge rapidly. Adjusting your printing preference to draft or greyscale mode helps prolong the life of the tri-colour cartridge during everyday document production.
