The HP-4100 was the first HP black toner cartridge to use an ARD. Unlike other chips, these only monitor usage not page counts.

After the OEM toner has been used up, the “toner low reached” code will be set to YES on the cartridge chip. Even after the cartridge is refilled, the printer display will still show “Toner Low” for the supplies status section of the menu. The main display will then show “Non HP Toner cartridge”. If the chip is removed, the toner low sensors will be disabled, and will not work again until a new HP cartridge is installed. Further testing on this is being conducted. Another possible use of this chip is when warranty repairs are needed. The machine will have a complete history of all the HP and non-HP cartridges used! Replacement chips are available.
