Ink Cartridge FAQ
17. What does the utility feature "Unknown" stand for?

Sometimes within the printer utility features, the Original Equipment Manufacturer (OEM) brand will be replaced by the mentioned "Unknown" when you use a compatible ink cartridge due to different data input on the chip set. This is for configuration purposes only and has no impact at all on the normal operation of your printer.
