Hi @arizonapoppies,
Welcome to the HP Support Community.
I'd be happy to help you!
I understand that you are having issues with the paper tray open.
Let's try to reset the Printer here as it helps remove any stored static electricity from the Printer which might be causing these issues.
- Turn the printer on, if it is not already on.
- Wait until the printer is idle and silent before you continue.
- With the printer turned on, disconnect the power cord from the rear of the printer.
- Unplug the power cord from the wall outlet.
- Wait at least 60 seconds.
- Plug the power cord back into the wall outlet.
- NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
- Reconnect the power cord to the rear of the printer.
- Turn on the printer, if it does not automatically turn on.
- Wait until the printer is idle and silent before you proceed.
Also, try connecting the Printer to a different wall outlet directly.
Check for obstructions inside the input tray. Make sure nothing blocks the paper from engaging with the rollers.
Hope this helps! Keep me posted for further assistance
