Hi! @3Dean, Welcome to HP forums.

I understand you are getting missing or failed printhead on your PC.

Don't worry I'd like to help you out.

Did you make any changes to your printer?

Excellent description and a great diagnosis done. It is greatly appreciated.

Please try few steps recommended below.

Update the printer firmware and check if it helps.

Resetting the printer can reset the connection with the printhead and clear any error messages. 

1.Turn the printer on, 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.Unplug the power cord from the wall outlet.

5.Wait at least 60 seconds.

6.Plug the power cord back into the wall outlet.

   note:

HP recommends connecting the printer power cord directly to the wall outlet.

7.Reconnect the power cord to the rear of the printer.

8.Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move. 

9.Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
