How do I set up the HP Envy Pro 6420?
Unboxing and initial setup
- Remove all packaging and protective tape from the printer and ink cartridges (Tech Nerds (reseller setup guide)).
- Install the HP 305 black and tri‑color cartridges: raise the ink access door until it stays in place, wait for the carriage to stop, then open the cartridge latch and insert the new cartridge after removing its protective tape (HP how‑to video (YouTube)).
- Load plain paper into the input tray.
Installing drivers and software
- Download the HP Smart app from HP Support (official manufacturer) for guided setup and driver installation.
- Alternatively, use the Windows or macOS driver package available on the same HP support page.
- During installation, the software may prompt you to print an alignment page (HP how‑to video (YouTube)).
Connecting to WiFi during setup
- Open the HP Smart app and follow the on‑screen prompts to connect the printer to your wireless network.
- For WPS: press and hold the Wi‑Fi button and Power button on the back for five seconds until the blue bar flashes. Then press the router’s WPS button within two minutes (Tech Nerds (reseller setup guide)).
- Place the printer near the router during setup for best results (HP user guide (PDF via Dustin)).
The implication: using the HP Smart app and WPS ensures the quickest setup for the Envy Pro 6420.
How to connect HP Envy Pro 6420 to new WiFi?
Why won’t my HP Envy printer connect?
- Check that the network is working, the password is correct, and restart both the printer and router (Tech Nerds (reseller setup guide)).
- If the printer repeatedly goes offline, try resetting the network settings via the printer’s control panel or the HP Smart app (HP Support Community).
- Ensure Wi‑Fi Direct is enabled when needed (HP user guide (PDF via Dustin)).
How to connect after changing WiFi
- Use the HP Smart app to reconnect to the new wireless network.
- If the app doesn’t detect the printer, press the Wi‑Fi button on the printer to activate the wireless setup mode, then use WPS as described above.
- For Instant Ink subscribers, the printer must stay connected to the internet at all times to ensure cartridge delivery (HP Support (policy page)).
Wireless issues on the Envy Pro 6420 almost always boil down to one of three things: the router is too far, the password is stored incorrectly, or the printer’s network stack needs a full reset. HP’s official guidance is consistent—start with a restart, then move to WPS.
The catch: if the printer fails to connect after multiple attempts, a network reset usually resolves the issue.
What ink cartridges are compatible with HP ENVY 6420e?
How to replace the ink cartridge?
- Turn on the printer before starting replacement (CompAndSave (ink cartridge retailer)).
- Raise the ink access door until it stays in place and wait for the carriage to stop moving (CompAndSave).
- Open the cartridge latch, remove the old cartridge, then insert the new one after removing the protective tape. Close the latch (CompAndSave).
- The printer software may indicate which cartridge needs replacement with an amber light (HP how‑to video (YouTube)).
Do all HP ENVY printers use the same cartridge?
- No. The HP Envy Pro 6420 specifically uses the HP 305 series (black and tri‑color) (HP Support).
- Other Envy models may use different cartridges (e.g., HP 62, HP 63, or HP 912). Always check the model number on the HP support page.
Using remanufactured or third‑party HP 305 cartridges can save you a few dollars per refill, but you risk reduced print quality and voiding the printer’s warranty. HP’s official cartridges are measured at 2.2 ml for black and 17 ml for color—third‑party equivalents often underfill.
The pattern: always verify cartridge model before purchase to avoid compatibility issues.
What are the common problems with HP ENVY?
Paper jams
- Open the rear access panel and gently remove any jammed paper. HP’s troubleshooting guide covers the most common jam locations (HP Support).
- Use paper that is within the supported weight range (60–105 g/m²) to reduce jams.
WiFi connectivity issues
- As noted above, restart the printer and router, check the network password, and use WPS if the printer is not detected.
- If the printer goes offline repeatedly, consider a static IP address assignment via the router’s admin panel.
Ink cartridge errors
- Ensure protective tape is removed from the new cartridge before installation (Tech Nerds (reseller setup guide)).
- If the printer shows an error code (e.g., E0), follow the HP forum guidance to reinstall the cartridges and reset the printer (HP Support Community).
The most common problems reported on the HP forum for the Envy 6420 are wireless disconnects and cartridge detection failures. Both are usually fixable with a network reset or a cartridge re‑seat, but if the error persists, HP’s online troubleshooting tools are your best bet.
The implication: most problems are fixable without professional service by following HP’s troubleshooting guides.
Why is HP ENVY discontinued?
What is HP Envy called now?
- HP began phasing out the Envy brand in 2024, replacing it with the OmniBook X series.

- No official end‑of‑life date has been announced for the Envy Pro 6420 driver support.
What this means: owners can continue using the printer with confidence due to the ongoing support.

For current HP Envy Pro 6420 owners, the choice is clear: keep using the printer with original HP 305 cartridges for reliable performance and continued support, or switch to third‑party alternatives at the risk of lower print quality and potential warranty issues. HP’s support page remains your best resource for drivers and troubleshooting, and the printer itself will keep working for years to come. For owners, the only real change is the brand name on the box of your next laptop – the printer itself remains fully supported.
