Canon Printers Can’t Recognise Canon’s Own Toner Cartridges
Canon printers use a rather annoying DRM that detects when you use a ‘fake’ toner cartridge, which basically amounts to any that isn’t manufactured by Canon itself.
But the chip shortage means that Canon is now forced to ship cartridges without the chip that signals the product is genuine – leading to its printers rejecting its own toner as fakes.
Canon’s support website admits it is “currently facing challenges in sourcing certain electronic components that are used in our consumables for our multifunction printers.”
It suggests a workaround which is, quite simply, to hit the ‘close’ button on the warning, and carry on printing.
