Hi @moraltx,

Welcome to The HP Support Community.  

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

I understand you are facing an issue with your HP ENVY Photo 7858 All-in-One Printer is having issues with color printing, particularly with missing Cyan, Magenta, and related colors on the diagnostics sheet. 

Here are a few troubleshooting steps you can follow to try and resolve this issue:
 

1. Check the Ink Levels:

• Open the HP Smart app or the printer software on your Windows 11 computer.
• Verify if the Cyan, Magenta, and other cartridges are low or empty. If any cartridge is depleted, replace it with a new genuine HP ink cartridge.

2. Perform a Printhead Cleaning:

• Open the printer software on your PC or go through the control panel on your printer.
• Navigate to Settings > Printer Maintenance > Clean Printhead.
• Follow the on-screen instructions to clean the printhead. You may need to run the cleaning cycle multiple times to unclog any nozzles.

3. Print a Test Page:

• After cleaning the printhead, print another diagnostics or test page.
• Check if the missing colors (Cyan, Magenta, etc.) are now visible.

4. Inspect the Printhead for Clogs:

• If cleaning doesn't resolve the issue, there might be a clog in the printhead. You can try a more thorough printhead cleaning by accessing the Advanced Cleaning option in the same Printer Maintenance settings.

5. Reinstall the Cartridges:

• Turn off the printer and carefully remove all ink cartridges.
• Inspect the cartridges for any damage or leaks.
• Wipe the cartridge contacts gently with a clean, lint-free cloth.
• Reinsert the cartridges and ensure they are properly seated.

6. Reset the Printer:

• Turn off the printer, unplug it from the power source, and wait for about 60 seconds.
• Plug it back in and turn it on to reset the system.

7. Update the Printer Firmware: Update the firmware on an HP printer 

• Make sure your printer's firmware is up to date. You can update it through the HP Smart app or the HP website.
