Hi @BRIGETTECLARK,

Welcome to the HP Support Community.  

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

The "Printing in single-cartridge mode" message on your HP ENVY 7640 could be due to various reasons, including issues with the cartridge or printer. Here are some steps you can take to troubleshoot the problem:

Check Cartridge Installation:

• Ensure that the new black cartridge is installed correctly. Remove it and reinsert it to make sure it's securely in place.

Verify Cartridge Authenticity:

• Confirm that you are using a genuine HP 62XL black cartridge. Counterfeit or incompatible cartridges may cause issues.

Clean Cartridge Contacts:

• Turn off the printer and disconnect the power cord.
• Remove the black cartridge and clean the electrical contacts on the cartridge and inside the printer.
• Reinstall the cartridge and turn the printer back on.

Update Printer Firmware:

• Check if there are any available firmware updates for your printer on the HP support website. Updating the firmware may resolve compatibility issues.

Check for Error Messages:

• Look for any specific error messages on the printer's display or your computer. This can provide more information about the issue.

Perform a Printer Reset:

• Turn off the printer and unplug it from the power source.
• Wait for a few minutes and then plug it back in.
• Turn on the printer and check if the issue persists.

I hope this helps. 

Take care and have a good day.-
