Answer: This error is displayed when trying to perform ink filling, test drawing, printing while an unavailable ink cartridge is installed.
1. Check the ink type is correct or not.
2. Reinsert the cartridge.
Wipe the Ink IC chip just in case if there are finger prints, dust, or oily condition.
3. Replace the ink cartridge to the other one.
