IMPORTANT NOTICE: If your printer has been updated to firmware version NK11K6 / YL11K6 and then cartridges may not be recognized, please try to reinstall your cartridges 2-3 times but don't exceed 5 times, and then the cartridges may be recognized again. Once the cartridges are recognized please don't take them out. WARM TIPS: Please disable firmware updates when the printer prompts to update and stop the firmware update notification. In this way, risk of chip unidentified error from printer firmware updates can be reduced.
