Hi @JBIRDHAUS,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you've already tried several troubleshooting steps for your HP Envy 6400 printer. If you're still facing issues with the new black ink cartridge not printing and you're getting faint blue when printing in color, here are some additional steps and considerations:

Additional Troubleshooting Steps

Check Cartridge Installation:

• Ensure that the new black ink cartridge is properly installed and securely seated in its slot. Sometimes, improper installation can prevent the cartridge from functioning correctly.

Clean Printheads:

• Perform a thorough printhead cleaning to ensure that any dried ink or debris is cleared from the printhead nozzles.
• You can usually find this option in the printer's settings menu or through the printer maintenance section on your computer.

Align Printheads (if possible):

• If your printer allows manual printhead alignment, try performing this function to ensure that the printheads are aligned correctly for optimal print quality.
• If the printer won't print the alignment page, there may be deeper issues with the printheads or printer mechanics.

Update Printer Firmware:

• Check for and install any available firmware updates for your HP Envy 6400 printer. Firmware updates can sometimes resolve print quality issues and improve overall performance.

Use Genuine HP Ink Cartridges:

• Ensure that you are using genuine HP ink cartridges. Non-genuine cartridges or refilled cartridges may not work properly with your printer and can lead to print quality issues.

Check for Ink Cartridge Issues:

• Verify that there are no issues with the new black ink cartridge itself, such as a defective cartridge or one that may have dried out.

Print Quality Diagnostic Page:

• Print a Print Quality Diagnostic Page from the printer's control panel or through the printer software on your computer. This page can provide valuable information about the status of your printheads and ink cartridges.

I hope this helps.

Take care and have a good day.
