Hi @Sadielucille,

Welcome to the HP Support Community.
 

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

I understand you're encountering ink cartridge issues with your HP Officejet 8600 despite having new and high-quality cartridges. Follow the troubleshooting steps below:
 

Reset the Printer:
 

• Turn off the printer using the power button.
• Unplug the power cord from the printer and wait for 60 seconds.
• Reconnect the power cord directly to a wall outlet and then plug it back into the printer.
• Turn on the printer and check if the error persists.

Use Genuine HP Ink Cartridges:
 

• Ensure that you're using genuine HP ink cartridges. Non-HP cartridges can sometimes cause error messages.
• If you have genuine cartridges, ensure they are correctly installed. Remove and reseat each cartridge to make sure they are properly in place.

Check for Firmware Updates:
 

• Although you've tried updating the firmware from a Mac, try using the HP Smart app or another computer to check for updates.
• If possible, download the latest firmware directly from the HP support website and install it.

Printhead Issues:
 

• As you've already replaced the printhead, ensure it’s properly installed. A loose printhead can cause cartridge errors.
• If you suspect the printhead is the issue, try reseating it by following these steps:
  • Open the cartridge access door.
  • Lift the latch handle on the carriage, remove the printhead, and then carefully reinsert it.
  • Lower the latch handle and close the cartridge access door.

Cleaning the Contacts:
 

• Power off the printer and unplug it.
• Open the printer and gently clean the electrical contacts on both the cartridges and the printhead using a lint-free cloth slightly moistened with water.
• Allow the contacts to dry completely before reinstalling the cartridges and the printhead.
  
  
  I hope this helps.

Take care and have an amazing day!
