I had the same error, I had to take the left side cover off, (looking at the front of the machine) and found a small piece of paper that ended up right in the middle of a sensor flag! Of ALL the places to land. I pulled it out, it worked, end of problem! When you get the side cover off, the sensor flag is located in the middle/bottom of the printer. Hope this helps, happy fixin'.

SOURCE: user error
. Turn the printer off, wait 10 minutes, and then turn the printer on. 2. If the message persists, reseat the fuser. If that does not work, replace the fuser. To check the fuser, turn the printer off and remove the fuser. Measure the resistance between the fuser connectors. If it is not within the proper range, replace the fuser. If there is not continuity between the fuser connectors neutral and hot with the fuser removed, replace the fuser. If the problem is not related to the fuser, replace the engine controller board.

You could try with different cartridge try to clean the contacts , check wether the cartridge is seated properly , make sure weather the strip is removed from the cartridge
If you use a HP original cartridge, then you shouldn't have this message.
Anyway you can print, it's only at startup that this message appears.
If it is a HP toner, then change it.

the printer is sensing that one of the motors are not turning.remove the cover from the left side .you will find the main drive motor,next to the motor you will find a sensor clean this sensor with some electronic board cleaner .be sure that the sensor it dry before turning the printer on.
