You'll probably have to delete the printer, the printer driver, the print queue and any preferences associated with those things. Then update the driver and re-add the printer.

Something is obviously messing up what the printer is reporting with regards to its supply level.

On my Lexmark I always see a warning that some "supplies" are low but it doesn't affect the ability to print. Thankfully.
