Hi @DianaK63
Welcome to the HP Support Community!
Thanks for posting your query! We're here to help you get back up and running.
I understand you need assistance with changing the default tray, Don't worry as I'll be glad to help.
Superb description and stupendous diagnosis of the issue before posting. Kudos to you for that. 😊
I appreciate all your efforts and patience.
By default, the printer pulls paper from Tray 1. If Tray 1 is empty and Tray 2 is installed and has paper loaded, the printer pulls paper from Tray 2.
On the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon.
Swipe up on the display, and then touch Tray and Paper Management.
Touch Tray Management, touch Default Tray and then touch Tray 1.
If this solution hit the spot, please come back and click "Accepted Solution" to help others find the answer. And if you'd like to say thanks, select "Yes" on the bottom left of the public post, as that would make our day!
Take care, and have an amazing day!
