HP ENVY Pro 6420 Ink Cartridge Replacement Guide

  1. Make sure that the printer is turned on and load a stack of plain white paper in the paper tray.
  2. Raise the printer's ink access door until it stays in place.
  3. The ink cartridge's carriage will automatically move, so make sure to wait for it to completely stop, before you proceed.
  4. Open the ink cartridge latch to release it, then carefully remove the ink cartridge from the slot.
  5. Get your new CompAndSave's HP 6420 ink cartridge, and open it over a sink or garbage can to avoid any messes in case it leaks, as sometimes, factories tend to overfill ink cartridges. Make sure to touch the black plastic part only, then remove the covering tape that is usually bright in color as well as the plastic protective case, if there is, before installing it.
  6. Insert the new HP ENVY 6420 ink cartridge into its respective slot, then put the latch down until it clicks into place.
  7. Close the printer's ink access door.

HP ENVY Pro 6420 Ink Cartridge FAQs

What ink does HP ENVY 6420 use?

The HP ENVY 6420 printer uses the standard-yield HP 67 and the high-yield HP 67XL black and tri-color ink cartridges. CompAndSave offers replacement HP 67 and HP 67XL ink cartridges that can match and provide the same quality as the original HP ink cartridges but at a much more affordable price.

Can I use different ink on my HP ENVY printer?

If what you mean by "different" is a different brand, then the answer is no. Using another brand of ink cartridge, such as Canon, Brother, or Epson, in your HP printer will not work. Aside from the fact that it will not fit, the chip sensor of these ink cartridges will not be recognized by your printer. You can, however, use remanufactured, replacement, or compatible ink cartridges. CompAndSave offers these types of ink cartridges, and they are designed to meet or even exceed the OEM specification. This means that you can get the same quality and performance without the hefty price tag. Also, using these types of ink cartridges will not void your printer's warranty. For more information, check our ink knowledge base, and you will be redirected to the right page.

Can I refill my HP ink cartridge?

Yes, you can refill genuine HP ink cartridges. You just need to have the right instructions and tools in order to do this, you may check our ink refill guide, and you will be redirected to the right page. However, doing this is not recommended since some parts of the ink cartridges wear out and might cause some printing issues. That is why we highly recommend replacing any empty ink cartridges. CompAndSave offers replacement and compatible HP ink cartridges that can provide the same quality as the OEM saving you from all the trouble of refilling an old ink cartridge.
