Hi there.

Thanks for the review and the description of your experience so far. While I’m glad you like the way your printer is performing, I’m sorry to hear that you had such a difficult time setting it up. I can wholly understand why a lack of instructional materials would be tremendously frustrating. With that in mind, I’ll suggest some resources that I hope will help you get the most from the device from here on.

To learn more about your printer and all its features, or for help solving problems, you can access user manuals, how-to documents, software updates and troubleshooting guides here:
- support.hp.com/us-en/product/hp-envy-pro-6400-all-in-one-printer-series/29256678/model/29256679

You can also visit a page on our support site that has diagnostic tools for various tasks and issues, including cartridge installation and connectivity. There you’ll find, among other things, a general-purpose tool called the HP Print and Scan Doctor. If you use Windows, the tool will help identify and guide you through solutions to a wide range of common printing and scanning issues. Visit that page here:
- support.hp.com/us-en/topic/diagnostics

If any issue arises and you need assistance, 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)
