@Moxnard, Welcome to the HP Support Community!
I understand your concern. The ways to remove any jammed paper/object is as shown in this document - Paper Jam Error
If this does not help, the printer has to be serviced/replaced. Please reach out to the HP Technical Support team in your region regarding the service options for your printer.
You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.
P.s: The bottom part o the printer is not customer accessible. You may remove it at your own discretion.
Keep me posted for any other assistance.
