OfficeJet Pro 8620 - Missing or Failed Printhead Error. How to reliably solve?

[print33]

After working without issue for years, my 8620 printer randomly popped up the infamous "Missing or Failed Printhead Error" while just sitting there.

Is there a reliable way to solve this? From what I read and everything that everyone has tried it doesn't seem to be a hardware issue but a software one. Is that true? Is there a factory reset or firmware update to fix it?

Welcome to the HP support community.

I understand that you are getting a Missing or Failed Printhead Errors, follow these steps to fix the issue.

Perform a power reset

1. Turn on the printer, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Wait at least 30 seconds.
5. Plug back the power cable straight to a wall outlet and printer without any surge protector.
6. Turn on the printer.

Update the printer firmware

Thanks for the suggestions. So far it hasn't worked. 

I tried the restart you suggested, the firmware is up to date, and I followed the link with more assistance and tried reseating the print head and it doesn't work.

Are there any other solutions? I like the printer and have had no other issues and only used HP ink. However, I am apprehensive about replacing the printhead as it is very expensive and from what I have read it isn't guaranteed to always work.
