The HP Officejet 8100 and 8600 has a “cartridge protection” feature. In the toolbox there is a tab named “HP Cartridge Protection”, where you can choose if you want to enable or disable this function. The default setting here is “enable” which results in the cartridges only working in this particular printer. If you install the cartridges treated with this “protection” feature in another printer, they will not work and a message pops up.
