I have instructions on how to clean the printer cartridges and pinhead electrical contacts, but after messing with the machine for and hour, I am still unable to center the cartridges in order to extract them. How is that done?

I understand you are receiving a "71.02.4A" error on the printer screen.
We can perform a factory defaults on the printer to resolve the issue
- The reset instructions are specific for your printer and performing those steps on a different printer may corrupt the device.
- I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
- In order to access your private messages, click the private message icon on the upper right corner of your HP Support Community profile, next to your profile Name or simply click on this link: https://h30434.www3.hp.com/t5/notes/privatenotespage
