@Opsie,

Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

1. Take out the cartridges. 
2. Unplug the power cord from the printer & wall. 
3. Wait for 30 seconds.  
4. Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector. 
5. Insert the cartridges back into the printer.

Also, try updating the printer's firmware.
 

I hope these steps help resolve the issue
