January 9, 2024 update:

I restored the printer to the original network settings per instructions in Chapter 10,  pg 142, of the User Guide, with no success. Could a tech support rep from HP please provide some guidance?

Thanks for your consideration.

Hi @Ouzel_Bishop,

Welcome to HP Support Community.  

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

It seems like you've already gone through several troubleshooting steps, which is a good start. Since the issue persists, here are some additional steps you can take.

Reset the Printer:

• Turn off the printer.
• Disconnect the power cord from the back of the printer.
• Wait for at least 60 seconds.
• Reconnect the power cord.
• Turn on the printer and check if the error persists.

Check Cartridge Installation:

• Ensure that the magenta cartridge is securely and correctly installed.
• Make sure there are no obstructions or protective tapes left on the cartridge.

Inspect for Physical Damage:

• Check the magenta cartridge for any signs of physical damage.
• Examine the electrical contacts on both the cartridge and in the printer for any damage.

Perform a Hard Reset:

• Turn off the printer.
• Disconnect the power cord from the back of the printer.
• Disconnect any other cables connected to the printer.
• Wait for at least 10 minutes.
• Reconnect all cables and power on the printer.

Update Printer Firmware:

• Even if you've already checked, ensure that you have the latest firmware for your printer model. Sometimes, reinstalling the firmware can resolve communication issues.

I hope this helps. 
 

Take care and have a good day.

Thanks for responding, Alden.

• I performed a hard reset per the steps you described, with no success.
  

-------------------------

• I attempted to update the firmware by downloading the executable file OJP8720_2105A.exe (release date Apr 5, 2021) from HP's support webpage at:
  https://support.hp.com/ca-en/drivers/hp-officejet-pro-8720-all-in-one-printer-series/model/7902033.

• I received the following message after installing the executable. I presume this means that I have the latest firmware.

I should have mentioned that the message is grayed out, and the checkbox is not select-able.

Also, I've done all the other steps you described in your message.
