When I turn on my Officejet Pro 8500A, it takes almost ten minutes for it to self-check and clean print heads before it will print. The printer is several years old and seems to take longer to self-check than it used to.

Welcome to the HP Support Community.
Is the Printer connected directly to the wall outlet? If not, please do.
Let's try a printer firmware update: https://support.hp.com/in-en/document/c02919168
Let me know if this helps.
