Smart Cartridge Service Check

Note: If you are unable to clear a “32-Unsupported Cartridge” User Error Message, make sure an Optra Se print cartridge is correctly installed in the printer. The cartridge is easily identified by the smart chip located on the top right side of the cartridge. Install another Optra Se cartridge before attempting to troubleshoot the printer. Check to make sure the smart cable is properly connected to J21 on the engine board. Check the print cartridge for any signs of damage or improper installation of the smart chip. Also check to make sure there is proper contact between the smart chip and the smart cartridge contacts.
