@Chuckb1513, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
The "Printer Door Open" error you're seeing especially after installing new ink cartridges can often be caused by a misalignment or obstruction around the cartridge access door. Here are some steps to help resolve the issue:

Check the Cartridge Door

• Open the cartridge access door fully.
• Inspect the hinges and surrounding area for any packing material, tape, or debris that might prevent the door from closing properly.
• Gently press the door closed until it clicks securely into place.

Inspect the Ink Cartridges

• Remove the newly installed cartridges.
• Check for any protective tape that might not have been removed.
• Reinsert the cartridges firmly until they snap into place.

Reset the Printer

• Turn off the printer using the power button.
• Unplug the power cord from the wall and the printer.
• Wait at least 60 seconds.
• Plug the printer directly into a wall outlet (avoid power strips).
• Turn the printer back on and check if the error persists.

Update Firmware (Optional but Recommended)

• Visit the HP Support page to ensure your printer has the latest firmware.

I hope this helps. 

Take care and have a good day.
