Thank you for contacting FixYa with your printer inquiry.
This error is most common when your toner cartridge has reached it's end of life. Sometimes it will alternate with "This cartridge has reached a low threshold error" which indicates you can keep printing but need to order a new toner cartridge. See page 155 of your support manual for more on this error.
See page #117 of your user guide for toner installation instructions.
If you have installed a new toner cartridge and receive "Remove Shipping Lock Error" that means you have not removed the protective strip on page 118 step #5.
You can order new toner cartridge from HP PartSurfer or retail merchant where printer purchased.
