4. Reinstall the cartridge and restart the printer.

NOTE：1. Please do not touch the chip when installing the cartridge.

             2. Please do not wipe the chip with alcohol.

Multiple Cartridge Issues:

2. Remove all newly installed cartridges.

3. Reinstall the previous cartridges (even if empty).
