Missing or Failed Printhead

[YesIcycledPower]

I am getting the Missing or Failed Printhead error that has been addressed multiple times in this space. I have an Officejet Pro 8620, and I use a Mac with the Ventura 13.7.3 OS. I have tried the HP published fixes, though I have not tried a replacement printhead, and there is no driver update available for download.

Exploring the forums, I see that HP Techs have often sent semi-full reset instructions to private inboxes. I'd like to give that a try if it seems appropriate. I am also hopeful for any additional instructions you can provide.

Thanks!

I suspect the printhead needs a good cleaning.

This link shows cleaning the 8600 printhead and removal is shown here.

This is another type of printhead cleaning, different from the above.

Cleaning and removing ink is shown below by our "Scullery" team.

An HP original video on how to clean the printheads by our experts. Yes, this can get messy, but it works. If your ink levels are good but you are printing blank pages then this is likely the solution.

Official HP advice on cleaning.

Some printers have a printhead cleaning procedure.

To clean the printhead on an HP printer, access the printer settings through the HP Smart app, navigate to "Print Quality Tools," and select "Clean Printhead"; this will initiate a cleaning cycle where the printer will automatically run a cleaning process to clear any clogs in the printhead

Many users ask for factory reset instructions thinking it will allow them to use non-HP ink.  Your 8620 is one of the few HP printers that can use any ink, not just HP ink.
