Cartridge Low: The chip does not display the amount of toner remaining, which may affect the number of prints and pages.
When installing the cartridge, if you see the computer "cartridge low" message, please skip to continue printing.
To use non-OEM toner cartridges properly, please turn off the printer's "Automatic Update" function; this will not affect daily printing or print quality.
Upgrading the printer system to the latest version may cause the chip in the toner cartridge to not be recognized by the printer, rendering it unusable.
Printers with activated HP+ service should use genuine toner cartridges
