Hi @YorkshireEm,
Welcome to the HP Support Community
I understand you are facing a toner issue with your HP LaserJet Printer. Not to worry I will help you to get a resolution to resolve the issue.
To assist better:
- Are you using genuine HP inks?
- Was there any recent update on the printer prior to the issue?
While you respond to that, Let's perform a power drain:
- With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
- Remove USB cable, if present.
- Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
- Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
- Turn on the printer and wait till warm-up period finishes and the printer is idle

If the issue persists, then please follow the steps mentioned in this document: HP LaserJet Pro Printers - A 'Toner Low' Message Displays (Product may vary but the steps are the same)
also try to clean the electric contacts on the toner cartridge
Open the toner cartridge access door.
Remove the toner cartridge from its slot.
Use a lint-free cloth to wipe the toner cartridge contact (E-label) on the top left of the toner cartridge.
NOTE:
Coffee filters work well.
