My printer has been flashing a red light and telling me I have no toner for the past 3 months, but is printing quite happily.
Can I adjust the waring so I get a red light when I am really nearly empty?
Hi there @Bill3285
The flashing red light means that the toner cartridge has almost reached its estimated cartridge life. It is recommended to replace the toner cartridge when this happens, though it can be used until it's totally empty! We wouldn't advise adjusting the wiring as this will void the warranty.
