If using genuine Canon cartridges, try reseating the cartridge. Power cycle the printer (turn it off, wait 30 seconds, and turn it back on). Update the printer's firmware to the latest version from the Canon website. If the error persists, the cartridge may be defective and require replacement, even if it's new.
