I cannot find anywhere that tells you how to factory reset this printer. I have been dealing with a black print head error . I have cleaned all of the contacts, and just replaced the printheads, both of them same time. When I was on the phone with HP initially, after troubleshooting with them, she told me how to factory reset this printer, I cannot remember what buttons she told me to hold while powering on. I am still having the same black printhead error even after replacement and would like to try to factory reset one more time before I give up.

You should power off the printer, then press and hold both Copy black and Resume, while holding them power on the printer and then you should see a spinning wheel.
