Hi, Tony.

I’m sorry to hear that you’ve not had the materials you need to learn how to operate your printer. Your review is brief, but your dilemma is clear – and your frustration totally understandable – so I’ll suggest some resources I hope will help you get your printer working to your satisfaction.

First, I can’t tell from your review whether you completed the setup and installation process. If you didn’t, you can access a setup tutorial specific to your printer on our support site. On the same page, you’ll find user manuals, how-to documents, troubleshooting guides and software updates. Find that page here:
- support.hp.com/us-en/product/hp-envy-pro-6400-all-in-one-printer-series/29256678/model/29256679

Next, you can visit another page on our support site that has diagnostic tools for various tasks and issues, including setup, cartridge installation and connectivity. Visit that page here:
- support.hp.com/us-en/topic/diagnostics

Finally, if you need further assistance with setup or anything else, I suggest that you contact us directly at +1 800-474-6836 so we can help you assess the situation and find a solution. (Please note that because of restrictions on personal movement and workplace attendance associated with the COVID-19 pandemic, wait times for agents are longer than normal. Thanks in advance for your understanding.) To expedite the process, I recommend gathering the following information before the call:

- Model number
- Serial number
- Your location
- Case number (from any previous contact with HP support)
