Splendid effort and fabulous description of the issue before posting. Kudos to you on that score.  You are a valued HP customer and it is paramount to assist you here. I take it as a privilege to share this platform with you. 

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Did you close the cartridge door completely?

Have you checked the cartridge door for obstructions?

Did you reset the printer?

As I see that you have contacted our HP Twitter support and they have helped to diagnose the issue, Before you contact our HP phone support, I would like to ensure you have followed these steps here:

Step one: Close the cartridge door completely

If the cartridge door is not completely closed, the error message displays.

Open, and then close the cartridge door of the product. Make sure that the door rests securely against the body of the product.

   NOTE:

To see how to close the cartridge door of your specific model, see the cartridge section of your product's User Guide.

Check the product control panel to see if the error message still displays.

If the issue persists, see the next step.

Step two: Check the cartridge door for obstructions

Bits of paper, packing materials, and tape might prevent the door from closing completely.

Remove any obstructions.
