Cartridge Low: The chip does not show the amount of toner remaining, which may affect print output and page count.
When installing the cartridge, if you see a "cartridge low" message on your computer, please skip to continue printing.
For proper use of non-OEM toner cartridges, please disable the printer's "Automatic Update" function.
This will not affect daily printing or print quality.
